I hate to say it, but what pops into my mind is Booty Call. Overall not a great movie, but the scenes involving the Saran Wrap and the convenience store employees are just insane. I was laughing so hard I had to pause the movie.
The mentioned Mel Brooks of course, although nobody mentioned Spaceballs. Python-related I second, as well as Galaxy Quest.
And then there’s Baseketball. You can’t beat the hospital scenes with the kid. Last request: “Can I have Chelsey Clinton?” “I think you’d have a better chance with Bill.” !!!
In no particular order:
Smokey and the Bandit
Caddyshack
History of the World Part I
Monty Python and the Holy Grail
Strange Brew
South Park Bigger, Longer and Uncut
Clerks
Chasing Amy
Dogma, and...
Fight Club
(yes, Brad Pitt and Edward Norton, the first time I watched it I thought what a great drama, once I got the joke I immediately watched it again and LMAO)
