Nurse!

Here's what Willis was talkin' 'bout ... Todd Bridges getting knocked the hell out -- on camera no less -- while trying to be a nice guy, backing up a friend in need.

The "Diff'rent Strokes" star recently helped his wheelchair-bound neighbor evict a woman living at the guy's house in the San Fernando Valley. We're told Todd's neighbor had asked him for help in the past, and Todd obliged this time too.

Well, things escalated quickly. Todd and the woman's boyfriend got into a verbal altercation, and next thing ya know ... Todd got sucker punched and laid out. It's pretty crazy ... in this surveillance footage, obtained by TMZ, you can see Todd was totally dazed from the hit.

We're told the guy fled the scene, but no police report was filed. As for Todd ... he tells us in a statement ... "No one likes to be sucker punched, but I am glad that I was there to help my neighbor, who was faced with a potentially dangerous situation."

Todd added, "Much rather it was me, and not my neighbor."

Laura Avila, the Dallas realtor who ended up in a coma after a botched nose job procedure in Mexico, has died ... TMZ has learned.

Laura's death comes days after her family made the difficult decision to move her to hospice care, following deliberations with her medical team.

As we reported ... Laura slipped into a coma after surgeons in Ciudad Juarez botched her nose job by incorrectly administering anesthesia. She had gone south of the border for the procedure to save some money ... and was stuck there for 8 days before her family was able to transfer her back to Texas.

Laura's attorney, Larry Friedman, tells us ... "She had the best of life in front of her until this tragic, unfortunate and senseless death. So that her death is not in vain, people should think of Laura before they look for cross border discount surgery. They should do their homework and investigate the experience, training and track record of anyone BEFORE they sign up."

He adds ... "Always LOOK before you leap!"

Joe Theismann says he was so shook after watching Alex Smith's brutal leg injury on Sunday, he couldn't sleep that night ... telling TMZ Sports it's brought back some painful memories.

Joe was at FedExField on Sunday when Smith took a hit from J.J. Watt that snapped his fibula and tibia -- a compound fracture where the bone broke through the skin.

Of course, Theismann was on the receiving end of a similar hit back in 1985 when Lawrence Taylor brutalized him on "Monday Night Football" ... causing the same injury.

"It was so surreal yesterday in the stadium," Theismann told the guys on the TMZ Sports TV show ... "to have what happened to Alex on the day it happened to me 33 years ago."

Joe says the similarities between the two are eerie.

"It was I think 166th game for Alex. Mine was 167. Basically, the same place on the field. Heck, I have a nephew named Alex Smith who's 33-years-old ... the whole thing is crazy."

Theismann says for the first time in his life, he couldn't really sleep after watching the injury in person -- saying, " I didn't really think this thing had bothered me as much as it did, and I think it probably got to me a little bit more."

Joe says he considers Smith a friend and plans on reaching out to the QB after giving him some space to deal with the injury.

The big message for Smith -- Theismann says there's light at the end of the tunnel ... so don't give up hope.

Bob Barker was rushed to the hospital for the second time in 2 months, but it sounds like it's another case of a bad back ... TMZ has learned.

The former "Price is Right" host was taken to Cedars-Sinai hospital by ambulance Sunday afternoon after suffering severe back pain at his Hollywood Hills home.

His manager tells us Bob is doing better now that he's under a doctor's care, and that this most recent hospitalization comes as a result of severe back pain related to his 2017 fall. He's fallen at least one other time before -- a 2015 spill that split his head open.

Sophia Floersch -- a German Formula 3 driver -- survived a terrifying crash during a race in China that easily could've killed her ... but left her with a fractured spine instead.

The 17-year-old was racing in the Macau Grand Prix Sunday when she reportedly collided with another driver, lost control on a sharp right turn, flew right through some crash barriers and landed in a photographer area. The accident is as bad as it sounds ... listen to the crowd scream in shock as her car gets airborne and smacks against a fence.

Incredibly, Sophia's racing team said she was conscious and stable, but had suffered a spinal fracture. They also listed her as "not fit to race," but did not say for how long. At least 3 others were also injured in the crash, including 2 photogs and the other driver.

Sophia later tweeted that she was "fine," and was going into surgery Monday morning. She added that she'd be providing updates soon.

David Arquette vows his incredibly bloody deathmatch was his last, but he's never going to take his foot off the gas.

We got David Saturday in L.A. ... a day after his brutal Game Changer Wrestling fight against Nick FN Gage. David kinda looked worse for wear, after Nick smashed a light tube against his face. Check out the huge scab on the side of his neck.

So, David says -- we're not sure if he's serious -- the only rematch he'll have with Nick will be in a UFC Octagon.

As for David just sitting back and becoming a spectator in life ... well, he scoffed at the notion. He's always been a fighter and never a couch potato.

Amy Schumer is back on her feet after suffering a pregnancy complication.

Amy was out and about in New York City Saturday ... this after she posted a pic of her in a hospital bed saying the baby was fine but she was suffering from hyperemesis -- AKA extreme morning sickness.

Amy canceled her Dallas show Friday night, but she was back in business Saturday, performing her comedy show in Newark, New Jersey, at the Performing Arts Center.

She's scheduled to perform Sunday in Pittsburgh.

Laura Avila, the Dallas realtor who ended up in a coma after a botched nose job procedure in Mexico, has been moved to hospice care ... TMZ has learned.

Laura's attorney, Larry Friedman, tells TMZ ... Laura's family made the difficult decision Saturday to move her into hospice, and the family believes her life is now in God's hands.

We're told the family decided hospice was Laura's best option after deep deliberations with her medical team.

As we reported ... Laura slipped into a coma after surgeons in Ciudad Juarez botched her nose job by incorrectly administering anesthesia.

We've just obtained shocking new video of Lil Pump moments after tear gas was dispersed at his concert ... and it's clear the rapper felt the full brunt of the attack.

You see a shirtless Pump rapping and hyping up the crowd as he stands on the edge of the stage, and that's when then the concert comes to a screeching halt as Lil Pump apparently starts smelling the gas.

Lil Pump has a puzzled look on his face as he slowly realizes something's not right, he lowers the mic and starts retreating off stage.

Backstage, Pump is nearly unconscious as he's getting treated by medics. Fortunately, he's able to recover and he climbs on top of his tour bus and finishes the show.

The crazy scene went down Friday night at Rock City in Nottingham, United Kingdom after someone tossed tear gas into the crowd.

The crowd may have gotten the worst of it because fans were sent scrambling as gas fills the auditorium. The building was evacuated and cops tell us at least two people were treated for minor injuries.

It's still unclear who launched the attack, but law enforcement sources tell us the incident was not terrorism.

David Arquette was bloody, mangled and nearly tortured Friday night in a wrestling match ... and there was NOTHING FAKE about it.

David was in a 'deathmatch' -- that's the name and not really an understatement -- at a Game Changer Wrestling event that went down at The Hi Hat.

The actor-turned-wrestler was up against Nick FN Gage and it was just brutal. Gage broke a light tube over Arquette's head. You see David grab his neck as blood pours from the area. Shockingly, the fight continues.

Toward the end, it looks like David gives up, climbing out of the ring, but then the 47-year-old hops back in as he bleeds profusely. Gage stomps on him, but David fires back by smacking Gage with a chair. It didn't take long ... David gets pinned.

After the match, David told his fans he needed a few stitches and he was fine.

Disney took "A Bug's Life" from the big screen and into the bedroom ... according to a new lawsuit filed by a woman claiming the Disneyland Hotel is infested by bed bugs.

According to legal docs, obtained by TMZ, Ivy Lizette Ewell Eldridge says she developed a severe skin rash over her entire body after an April stay in the Disneyland Hotel in Anaheim, and the hotel failed to tell her about a bed bug infestation.

In the suit, she says bed bugs latched onto her body while she slept and "sucked her blood until they were gorged." She claims the rash was so bad, she needed medical treatment.

We've obtained photos of her alleged injuries and, yeah ... they're gross.

The coach who witnessed his player eat a VICIOUS cheap shot elbow tells TMZ Sports he couldn't be happier his team did NOTHING in retaliation.

The video's insane ... Fitchburg State was playing Nichols College (both D-III teams) Tuesday night in Massachusetts ... when FSU's star Kewan Platt intentionally elbowed Nate Tenaglia ... sending him to the deck.

A lot of people wondered where the hell Nate's teammates were ... and why didn't they step up and return the favor?

Nichols head coach Scott Faucher knows why ... he's got a squad full of smart dudes.

"We have older guys that have been through it. They understand what a retaliation might mean, in terms of consequences and things like that. So, their focus is on the next play."

Coach says he trusts Fitchburg to handle the situation ... and they did -- indefinitely suspending Platt from the basketball team and the university's campus.

As for Nate ... he somehow managed to eat the elbow and live to shoot another 3.

A guy who claims he got beat up during a brawl at Jay-Z's 40/40 Club is now looking at the dust-up with 20/20 vision ... and his sights are set on suing.

Jose Irizarry just filed suit against Hov's New York-based sports bar and lounge, alleging the venue's lack of adequate security combined with insufficient crowd control led to him getting seriously f***ed up during a melee that broke out this past March. For the record ... Jay isn't named in the lawsuit.

In the docs, obtained by TMZ, Irizarry claims he was minding his business at 40/40 when all of a sudden a huge fight broke out between some attendants and security ... and he became collateral damage.

Irizarry says he was struck in the head and body during the brawl, and endured pain and suffering, lost wages and medical expenses that he wants the club to cover.

Dez Bryant's callin' his Achilles surgery Tuesday a huge success ... straight from his hospital bed -- while feelin' loopy as hell!!!

The wideout, after just 2 days with the New Orleans Saints, popped his Achilles tendon in practice last week and needed surgery to repair the mess.

That operation just went down ... and, per a completely drugged out Dez, it went well!!

"I just finished surgery. I'm out," Dez says with a laugh. "God is great. Thank everybody for the support."

In case you didn't believe the superstar receiver ... Dez put his doc on the screen to confirm the good news.

"Everything went well. Success! Nothing to worry about."

11/13 9:30 AM PT -- LeVert reportedly dislocated his right foot and ankle in the incident ... and he can return later this season.

Brooklyn Nets star Caris LeVert suffered a nasty leg injury Monday night that was reminiscent of the injury that sidelined Gordon Hayward for an entire season.

LeVert landed awkwardly after going up to attempt to block the Timberwolves' Josh Okogie and appears to have snapped his ankle. You can see how much pain he's in right away as he covers his face. LeVert had to be taken off the court by stretcher.

The injury is eerily similar to the one Hayward suffered last year during his debut with the Celtics. Hayward also landed awkwardly on his ankle, and had to undergo surgery to recover.

Yair Rodriguez might've handed out the greatest knockout in UFC history ... but he didn't escape unscathed ... 'cause dude's whole body is jacked up -- from head to toe.

Literally.

Rodriguez -- fresh off his INSANE last second KO of the "Korean Zombie" -- joined the guys on the "TMZ Sports" TV show (airs nightly on FS1) ... and showed off his battle scars.

"My nose is broken, and both my eyes are purple" ... Rodriguez told us.

But, the worst part?

His freakin' feet are ridiculously swollen ... so bad that he can't even move around on his own.

"I cannot walk without crutches, right now."

The fight was unbelievably entertaining ... and fans are already calling for a rematch.

So, is Yair down for another scrap?

"I'm always trying to move forward on my life and my career. I don't know what's coming next. Korean Zombie is a fighter I really respect a lot. I have tons of respect for him, of course."

"If I ever have to fight him again, it'll still be an honor for me to fight him."
