"I wake up in the morning and piss excellence" I could recite most the lines! It's a perfect end of kind of night movie along with a ton more comedies like Horrible bosses and the extra amazing Stepbrothers.
Better off Dead: Will you take a check? Gee Ricky--I'm sorry your mom blew up! The Big Lebowski. Fear and Loathing. Uncle Buck: but jus--but--I can --It's jus-lemmie jus-----------awwwwwww.
Shot in the Dark--the original with Peter Sellers. And several other Inspector Cluseau flics are worth watching.
I have a particular fondness for the first three Cheech and Chong movies (Up in Smoke, Next Movie, Nice Dreams). Hard to pick my favorite of them, though. Probably Next Movie.
