Airplane is the first movie I saw where I actually laughed out loud. Later on, it was Happy Gilmore. There have obviously been other funny movies that I've seen, but these 2 stand out.
Agreed. Also with OT's pick. Add: Some Like it Hot Mrs. Doubtfire Stripes Big Fast Times at Ridgemont High Raising Arizona Tootsie
the funniest scene i think i've ever seen..."come on everybody. we're going streaking!!! come on, snoop. snoop a loop. bring your green hat."
