Scott Baio got into a verbal altercation at a golf course in Los Angeles this week -- but don't worry, Chachi wasn't in any real danger ... cause the whole thing was staged.
TMZ obtained photos taken this week, showing Baio getting into it with
TNA wrestler
Eric Young -- and we're told the whole thing was shot for a comedy segment that will air on
Impact Wrestling this Thursday on
Spike TV.
Check out the gallery to see Baio in all his glory.
Henry Winkler and
Scott Baio -- who both co-starred with
Tom Bosley on "
Happy Days" -- tell TMZ they are both shocked by his death ... but remember their former castmate as a "great man."

Winkler tells us, "I saw him before I ever got to Hollywood on Broadway, and he was great.
And then I got to act with him for 10 years and he was great. Tom
Bosley was our mentor. He was a true artist ... a great husband, and a
fabulous father and grandfather. He will be sorely missed, but never
forgotten."
Baio adds, "He was a good man who taught me a lot about the business and business itself. He was a professional guy ... I'm sad."
UPDATE: Ron Howard tells TMZ, "I'm so saddened by the loss of our wonderful Tom Bosley. Remarkable on so many levels, Tom's insight, talent, strength of character and comic timing made him a vital central figure in the Happy Days experience."
Ron adds, "A great father and husband, and a wonderful artist, Tom lead by example, and made us all laugh while he was doing it. My last conversations with Tom reflected the love of life and peace of mind that he always maintained throughout his full and rewarding life. I miss him already."
Possible killer
Robert Blake ran into 49-year-old former "
Happy Days" star
Scott Baio outside a Starbucks yesterday.

When Robert Blake went back inside the Starbucks to get something, Baio ran away.
The only reason we're showing you this video of
Scott Baio first thing on a Monday morning: An earthquake measuring 5.0 on the richter scale happened while we were filming.
Former "All My Children" male-to-female transgendered lesbian British rocker, Zarf, has reappeared as Scott Baio's brunette psychologist on his new VH1 reality show! Zarfie loves Chachi! Well, not really.

Although Dr. Alison Arnold on "Scott Baio, 45 and Single" sure looks like the trannylicious Zarf, she is, in fact, a biological woman ... and has a resume to boot! Ali's worked with Olympic athletes, politicians and many other celebrities. She helps people and organizations "take off" limiting beliefs, and "scream" their greatness in the way they live, work, and love. Just like Zarf did!
You go, girl!
Believe it or not, "Superbabies: Baby Geniuses 2" is not the worst thing Scott Baio has been in.

TMZ has learned that along with blonde bombshells like Pam Anderson, Heather Locklear and Nicollette Sheridan,
the 45-year-old '80s TV hunk once bumped uglies with Liza Minnelli! You heard correctly. Liza with a WHAT?!!
We're told by
extremely well-placed sources that Baio and the 61-year-old re-assembled diva spent a night together years ago and made beautiful, er, music together. Charles in charge!
Who knew David Gest had Scott Baio's sloppy seconds?!
LG Mobile threw a huge bash on Tuesday to celebrate their latest cell phone, and rang up some of the biggest stars -- from 1982!

With everyone from Erin Moran and Scott Baio to Gary Coleman and Sherman Helmsley dusted off and carted onto the Paramount lot, the red carpet looked more like a "Battle of the Network Stars" rerun than a paparazzi-worthy event! RIP Howard Cosell.
To keep the has-been lineup fresh, 21st Century sub-lebs like Tara Reid, Bai Ling and Jesse Metcalfe were also on on hand for the festivities. Where Are They Now?!
While everyone and Dina Lohan can lay claim to having thrown a few back with Britney and Lindsay, how many can say they partied with Joanie Cunningham! Happy Days indeed!
San Fernando Valley lothario Scott Baio, who has allegedly had his way with numerous Hollywood honeys -- including Heather Locklear, Pamela Anderson, Denise Richards and Nicollette Sheridan -- is now 45 and still single. What?

Chachi, seen here with pal Jason Hervey (Wayne on "Wonder Years"), is now joining the rank ranks of
Flava Flav and Bret Michaels on VH1 to search for a soulmate. The show will follow Baio as he tries to find himself while enduring a mid-life crisis, wondering why he's still single and unable to settle down -- not even with his current girlfriend, Renee. Walk away, Renee!
Baio has agreed to fully surrender the next eight weeks of his life to exhaustive introspection with a life coach, Dr. Alison Arnold, otherwise known as "Doc Ali." Doc Ali will try to get to the core of his problem, and Scott will be forced to revisit some ex-girlfriends -- and take a vow of celibacy.
If the lengthy list of Scotty's beam-ups is true, a vow of celibacy might not stick!
There's still time to lay down a side bet on whether or not Prince's pants will split during the Super Bowl halftime show. But quite frankly, there's about as much chance of that happening as there is of Prince dedicating "Sign o' the Times" to one of these folks:
Paris Hilton: Joe Francis is spilling the beans about her oral sex skills on Howard Stern; reports from the set of "The Hottie and the Nottie" suggest you're flubbing your lines. Late in the week you managed to top all that via the release of another grainy video on the Internet, courtesy of that joker who turned the contents of your storage locker into ParisExposed.com. Instead of night vision, this one is in stereophonic fright vision, with you uttering both the Isaiah Washington F-word and the Michael Richards N-word while dancing the night away with sister Nicky and some frat boys. Hot it's not, and more than likely, by the time this Z List hits the TMZ website, you will have already humbly offered up the A-word to make amends. We never thought we'd say this, but it's actually better for you to put a boyfriend in your mouth than your own foot.

Pull out your legwarmers and start teasing your hair -- the '80s have returned.
All your favorite stars from back in the day were out in force last night, including the one and only Scott Baio, proving that while his career may be dead, Chachi himself is not. And though we're not sure you'd want it, the former "Charles in Charge" star even passed off some of his legendary "mojo" to you lucky viewers.
Other stars at the VH1's "Totally Awesome" launch party included "Family Ties" Tina Yothers, "Wonder Years" older bro Jason Hervey, Poison rock star C.C. DeVille and "The Hulk" himself, Lou Ferrigno -- who all
got down on the dance floor.
No '80s evening would be complete without some killer tunes from the synth-heavy age of music, with the highlight of the evening being Tiffany singing her breakout hit "I Think We're Alone Now." She's clearly a long way from the mall tours of her youth ... though we're not sure that's a good thing.

For some, like Mel Gibson celebrity impersonator Rohn Evans or the pair of anonymous Ohio jokesters posting anew on the satirical blog "Mel's Musings," the actor's PCH flare-up is a bonanza. But for most others in the Zone, the events first reported by this website are akin to the French movie poster tag line for Mel's 1998 action flick Tequila Sunrise - "Un Cocktail Explosif."
