Nurse!

Jimmy Fallon almost had a finger amputated and spent 10 days in ICU ... and it was all over his wedding ring.

Fallon talked about the freak accident on "The Tonight Show" Monday ... his first appearance since the injury.

TMZ broke the story ... Fallon was rushed to the hospital June 26 after a severe injury at his home.

Fallon describes how he tried to break a fall in his kitchen and his ring got caught on the counter, almost ripping his finger off.

Gnarly.

"Buffy the Vampire Slayer" star Nicholas Brendon has checked himself back into rehab after a bizarre incident where cops found him bleeding in an alley.

According to law enforcement sources ... Brendon got into an argument on July 3 with a woman at her apartment, smashed a window with his bare hands ... and then bolted. Firefighters responded and found Brendon in an alley, bleeding from the hands.

Brendon was transported to a hospital, but did not get arrested. He checked himself into rehab 3 days later.

Scary moment last night ... when Verne Troyer fell hard while dancing on the DJ booth at a nightclub and smacked his head on a speaker -- but fortunately, we're told HE'S OKAY!!!

46-year-old Troyer was dancing his ass off at LIV nightclub in Miami and having a blast during Cedric Gervais' set -- but you can see in the video, he loses his balance and tumbles backwards until he hits the speaker.

The good news ... the owner of the club, Dave Grutman, was there to quickly help Troyer up -- and Verne let everyone know he was ready to keep the party going!

Verne's a tough dude -- plus, he's been through worse ...

Joni Mitchell's prognosis isn't as dark as it's been reported -- the folk music legend's attorney says she's making amazing progress since an aneurysm ... and the words "full recovery" have been used.

According to court documents, an attorney appointed to Mitchell's conservatorship case visited the legendary singer/songwriter on June 26 at her home.

The attorney, Rebecca Thyne, said Mitchell was feeding herself lunch when Thyne arrived and they talked about the care she was receiving from long-time friend, Leslie Morris. In the docs, Thyne says Mitchell said she wants Morris to continue as her conservator.

Thyne's encounter is interesting ... multiple reports, including one account last month from Joni's friend David Crosby, claimed she was not able to speak.

Thyne concluded, Joni was making "remarkable progress" -- and added she's "expected to make a full recovery."

Mitchell was hospitalized on March 31 after being found unconscious in her home after suffering an aneurysm.

Jerry Weintraub died after a 30-hour hospital stay that ended with a bowel rupture that triggered 2 heart attacks ... family sources tell TMZ.

We're told Weintraub was staying at the Biltmore Hotel in Montecito over the weekend. He attended a 4th of July bbq Saturday night, and began feeling ill shortly thereafter. He thought he had contracted food poisoning, but things got worse as the evening progressed ... and at 3 AM Sunday his partner, Susie, called 911.

Our sources say doctors quickly determined Weintraub had a bowel obstruction. Weintraub got a CT scan shortly after he was admitted, but we're told doctors determined there was nothing alarming.

Weintraub laid in the hospital bed for 30 hours, but we're told doctors were still not able to identify the problem. Weintraub -- who hated hospitals after nearly dying 6 years ago from an infection after back surgery -- insisted at around 4 AM Monday that he be discharged. We're told the staff told him he could not be discharged and continued to monitor him.

Just after 6 AM Monday Weintraub had a heart attack, and a 2nd CT scan revealed he had suffered a bowel rupture. Doctors don't know when the rupture occurred, but it sent poison throughout his body. Weintraub was taken to ICU, where he suffered a 2nd heart attack, 2 hours after the first.

We're told prior to the initial heart attack, Weintraub was not only conscious ... but joking with people in the room.

As we reported, Weintraub died at the hospital at 12:45 PM Monday.

Seems Jason Pierre-Paul went to painful lengths to keep his fireworks injury under the radar ... NOT calling emergency services after the mishap ... law enforcement tells TMZ Sports.

As we previously reported, the NY Giants superstar injured his hand during a 4th of July fireworks accident at a home in Broward County, Florida.

But get this ... when we called law enforcement officials in Coral Springs, Pompano Beach and Fort Lauderdale -- none of them had any record of ANY incident involving JPP. Neither did any Fire Department in the area.

In fact, one law enforcement source tells us everyone is aware of the incident ... but there has been no "formal report" was ever made.

So, what does it mean? It could mean that Jason's injury was not as bad as first reported and he didn't feel the need to call for emergency medical assistance.

Then again, it could also mean the injury WAS horrific ... and JPP was willing to suck up the pain and seek medical attention to limit the amount of people who truly knew the extent of his injuries.

Jimmy Fallon's healing his aching left hand in style ... hitching a ride to the Hamptons to close out the holiday weekend.

Jimmy's injured fingers and hand were fully wrapped in a cast Sunday in Manhattan as he hopped a helicopter bound for the Hamptons -- 10 days after he nearly lost a digit falling at home.

The 'Tonight Show' is in repeats now ... so we're guessing Fallon's using his time off for some quality R&R out on the Island.

Little advice, Jimmy? Keep that thing out of the sand.

It's pretty disgusting but also not unexpected ... someone is shopping a pic of Bobbi Kristina laying at death's door in a hospice.

The photo was shopped to us ... we passed. It was taken earlier this week at the facility outside of Atlanta. A woman is hovering over Bobbi Kristina in the photo ... we're told it's a family member.

As for who shot the photo ... we're told it's "an extended family member."

Bobbi Kristina's family is pissed over reports that Oprah Winfrey and Tyler Perry orchestrated a Hail Mary to save BK's life ... when they had nothing to do with it.

Sources close to the Houston and Brown families tell TMZ ... it was Pat Houston -- and not O or TP -- who organized a medevac airplane to bring BK to meet with a specialist in Chicago.

We're told the family feels the report makes them seem like they're relying on celebs to take care of BK ... when that just isn't the case.

There's only so much Bobby Brown can take ... which is why his friend of 40 years, Ricky Bell says there's no way to comfort him over the impending loss of Bobbi Kristina.

Ricky, one of Bobby's New Edition mates explained it's hard to find the right words when he talks to Bobby, because he's suffered so many tragic losses (4 of them) in the last few years. He added ... his heart goes out to the Brown and Houston families.

The Houston and Brown families came together again Monday as they prepare for the death of Bobbi Kristina.

Pat Houston left the Peachtree Christian Hospice near Atlanta, hand-in-hand with Tina Brown, Bobby Brown's sister.

The families were in a bitter feud for months over the care and the estate of Bobbi Kristina, but it appears there's at least a temporary detente.

Comic book legend Stan Lee was rushed to the hospital Sunday morning ... TMZ has learned.

According to our sources, the "X-Men" and "Fantastic Four" creator was taken from his Hollywood Hills home to Cedars-Sinai Medical Center.

The nature of the emergency is unclear ... he just said he didn't feel well.

It sounds like he's on the mend, because a rep for Lee tells TMZ he will be at the "Ant-Man" premiere in Hollywood Monday night.

The 92-year-old is also responsible for Spider-Man, The Hulk, Iron Man and Thor, among others.

Lee was fitted with a pacemaker in 2012.

Redneck extraordinaire Ethan Schneider is lucky that chicks dig scars, cause a drunk sword trick gave him a big one after almost slicing his nose clean off.

Ethan tells TMZ his schnoz is back on and working just fine after a bad stunt at the hands of a drunk hillbilly wielding a samurai sword.

4 hours of surgery and a slew of stitches later, Ethan got his sniffer back. He can smell but has no feeling … and doctors aren't sure if it will ever come back.

That's called a good result.

Shia LaBeouf was sporting fresh head gear -- as in layers of bandages -- the morning after putting his head through a glass window ... and we got the first pics.

TMZ obtained these shots of Shia in Williston, ND on Thursday -- the day after he got 20 stitches and 13 staples. We broke the story ... Shia cut his head, left ear, and right index finger while shooting a scene for his movie, "American Honey."

The director and Shia agreed he would do the stunt himself ... for realism, and yes -- he really bled. A lot. We're told he actually gave it a 2nd go, and nailed it without injury.

Stuntmen? We don't need no stinkin' stuntmen.

Jimmy Fallon and his single working hand are looking for a little sympathy -- he just gave us a first look at the injury, and an explanation for what happened early Friday morning.

Jimmy's left hand is heavily bandaged and elevated in the pic he posted from his hospital bed. He says his ring got caught on the edge of a table when he tripped and fell at home -- and he damn near ripped a finger clean off his hand.

At least the 'Tonight Show' host can still count on his right hand for important things.

Jimmy Fallon is laid up in a New York City hospital this morning after having surgery on his hand ... TMZ has learned.

After taping his show on Thursday ... we know Jimmy did dinner at Upper East Side restaurant Scalinatella. He posed for pics with a table full of female fans.

We're told Jimmy left the restaurant around 9ish ... and went home.

His rep says the injury to his left hand happened early this morning in his apartment. He went to the hospital, and a specialist recommended he have surgery immediately.

Friday night's taping of the 'Tonight Show' has been cancelled, but Jimmy's rep says he's expected to make a full recovery.
