Umm.. Let's see here. George Carlin, Robin Williams, Katt Williams @ Stand-up. Other than that any comedy movie or hilarious cartoon. Most exciting movie I've watched high that was funny was Guardians of the Galaxy. Toked up in the bathroom there, got stoned as hell, and went in to watch. The whole time I was giggling, haha.
Hangover trilogy, maybe project x...not sure if that's a comedy. Any cheech and chong, how high is a trippy movie...
