The only problem was: It wasn't Jim Carrey. It wasn't even Jamie Kennedy. In fact, the guy looked less like Carrey and more like that ventriloquist dummy from Goosebumps. People should have really seen through the ruse, though, when he took the stage and instead of quipping "All righty then" or "Somebody stop me," he didn't say a goddamn word ... because the impostor didn't speak English.

"Are we done here? I gotta be Jason Segel at another ceremony."

Then he fired a confetti gun in the air like a maniac, because apparently people in Prague think Jim Carrey is Rip Taylor.

After that, "Jim" just walked away, leaving the confused presenter disappointed that she didn't get to ask the beloved comedian about his body of work.

"But he'd only answer questions about Layer Layer and The Musk."

Insanely, even after a guy who didn't remotely look like Jim Carrey walked on stage and treated their awards show like a tacky wedding reception, the show's host vehemently asserted that it was the real Carrey, stating that skeptics simply "did not have a chance to recognize him." Of course, the whole thing turned out to be an elaborate prank by a TV show that wanted to get some random nobody on an awards show. At least that way the winners in the technical categories didn't feel so alone.

Pavel Sfera is a professional Bono impersonator, which frankly doesn't seem to consist of much beyond owning a leather jacket and the right sunglasses. Sometimes he gets paying gigs as a celebrity lookalike, but other times he just hangs out at places where Bono's supposed to be, such as outside a stadium before a U2 concert -- which whipped fans into a frenzy despite the fact that you could hear the band doing a sound check at the same time.

"Those are just my bandmates, The Edge and ... uh, Ringo?"

On one occasion, Sfera got more than he bargained for. Hanging out at a party in a recording studio, he was confronted by right-wing blogger and author Jason Mattera. In an ambush interview, Mattera takes "Bono" to task for U2's business practices, never realizing that was basically talking to a human equivalent of a Madame Tussaud wax dummy.

In the video, Sfera doesn't even have an Irish accent, which seems like kind of a giveaway, considering Bono is the most famous Irishman that isn't peddling marshmallow cereal. Also, presumably because Sfera had some kind of dead uncle who taught him about the responsibility of wielding his great power, he has rules for pretending to be Bono, one of which is that he never actually tells people he's in U2 ... but he won't correct them for thinking it. So, while he never comes out and says, "I'm not Bono, you stupid jackhole," he actually answers all the questions honestly, denying that he did any of the things Bono had done.

Jason Mattera
Earlier on, Mattera got some pretty shocking statements from a coat rack
that kinda looked like Chris Martin.

Of course, none of these subtleties were picked up by Mattera, who not only concluded the interview, but went home, took the time to edit it together with a bunch of dumb graphics and over-dramatic music, and then uploaded it to the Internet.

The video was picked up by a number of conservative websites, then immediately taken down when it became painfully obvious that it wasn't Bono. After the fact, Mattera claimed that he was "punked," a reference to that show where Ashton Kutcher stands silently at a social gathering and somehow tricks strangers into confronting and filming him.

With America not ready to believe in the necromancing powers of Hugh Downs and Barbara Walters, it came out that this guy's story was total bullshit. He didn't even share the same name as the original actor, William Thomas, who died in 1980. This wasn't a small incident, either: The producer of the segment was forced to resign, leading to the cancellation of upcoming interviews with Groucho Marx, Elvis, and Joan of Arc.

Most insanely, Bill English, who it seems was a few members short of a He-Man Woman Hater's Club, still continued to insist he was Buckwheat, appearing on TV with the actor who played Spanky to debate the matter.

"Fine, I'm not actually Buckwheat. I'm actually you."

The merits of some of Warhol's art is up for debate, but come on, this is just laziness. It's not a stroke of conceptual genius; it's an episode of Three's Company. Warhol dressed actor Alan Midgett in a wig and sunglasses and sent him on the road, letting him keep the money colleges shelled out because he'd appeared in some of Warhol's films for free. Of course, the only people Warhol cheated were the youth of America -- but, hopefully, ruining their burgeoning love of art was worth not having to pack a bag and leave his penthouse.

Surprisingly, the hoax actually worked for several gigs, despite the fact that Midgett's transformation into Warhol seemingly amounted to purchasing an Andy Warhol costume from a Halloween Superstore.

"You hired me a guy called Midgett? No, I wanted a mini-me, dammit!"

The plan's ultimate undoing was the fact that Warhol's impersonator didn't know what the fuck he was talking about. Complaints of how terrible the show was, coupled with the fact that an art teacher who had met Warhol became suspicious, led to the truth coming out. Warhol claimed he sent a fake in his place because he was more "talkative" and "dashing," which is code for "I don't wanna put on pants today (or this whole month)."

Would anyone even recognize this guy out of costume? The answer is nope, no way, as proven in the early '90s when a man came forward claiming to be Criss, now homeless and living on the floor of a Santa Monica men's room.

VH1
Which, to be fair, should be the expected result of rock-and-rolling all night and partying every day.

After the story broke in a tabloid, KISS fans gave the guy a place to stay, celebrities like Roseanne and Tom Arnold visited him, and a woman who claimed to date Criss in the '80s bought him a first-class plane ticket to Boston -- because even a guy who uses urine-soaked tile as a bed shouldn't be forced to endure the nightmare of flying coach.

Meanwhile, anyone who had bothered to properly look into the situation probably would have found that Peter Criss was living comfortably with his wife and 8-year-old daughter. He didn't even know about this impostor until a visit to see his dying mother, where his "freaked-out" brother asked him what the fuck was going on.

It turned out that the homeless guy, whose real name was Christopher Dickinson, lost his ID and just started calling himself Peter Criss because he was "mixed up from alcohol" (the alcohol also probably prevented him from conjuring the name of a cooler rock star to impersonate). Eventually, both Criss and Dickinson appeared on Phil Donahue's show to clear everything up.

By this point, Criss was working as a Rod Stewart impersonator.

Hopefully the real Criss never befalls some kind of Ponzi scheme, because if he ever does end up on the streets and needs help, no one will believe him.

Of course, you can't get into the actual theater without a ticket ... but you can get into the premises and be treated to free food and booze.

Unfortunately, he didn't go to the bathroom to find out what sort of free stuff you get offered there.

He also got into a VIP after-party with no ID, something even goddamn Beatles can't always manage.

"I've seen Totally A Real Movie No Seriously at least five times."

But even if it was a real Oscar, there's absolutely no reason he should have been given the keys to a BMW that wasn't his after claiming to lose his valet ticket ... which is exactly how his night ended.

Under L.A. law, the attendant who hesitated had to be executed.

At other points during the night, he got free stuff from a 7-Eleven, a ticket to the movie he supposedly won for (The Theory Of Everything), and a shitload of hugs from people who "remembered" his speech. Look out for the sequel, where he pretends to have a Golden Globe and people punch him for no reason.
