the longest single set at the laugh factory lasted 7h and 34m (by Dane Cook in 2008).

I almost fist fought him in front of the LA Improv. He hated me because I do a really good impression of him, and he belittled me from the stage at this very Laugh Factory a week before, ran into him and he was shouting and I mean shouting in the middle of Melrose threatening to sue me for posting a video online of his set and stealing his jokes (ironically, before his big expose for stealing jokes), and it was also not the case at all... Then, after we all settled down, he got me kicked out of the Improv later that night, it was squashed for hours, that was probably the most immature and little bitch way to "best someone" that I've ever seen in my life.

Best part is that I went into all of that respecting the hell out of him as a comedian, never meet your idols guys, most of them suck.
