America's favorite prankster's behavior was even too much for a roast, where normally anything goes. Steve-O didn't even make it a half hour before he got the boot at a roast for Gene Simmons Tuesday night at the Key Club in West Hollywood, according to our L.A. sources Sitting among other roasters Carrot Top, Danny Bonaduce and other raunchy comedians on stage, Steve-O must have not had time to hit the john before the taping started. So naturally, he dumped his beer out on stage and pissed in it....TWICE! He must have just gotten a warning at first, but after funnyman Jeffrey Ross cracked that "Steve-O could sell his boogers for a hundred dollars a gram" he got peeved and did it again! That's when he was asked to leave. Our spies knew there was going to be trouble when they saw him getting sloshed at the Rainbow, next door, before the taping. LOL! Stay tuned to see if this roast footage makes the cut when it airs on A&E!
