This is Spinal Tap
Ferris Bueller's Day Off
History of the World, Pt. 1
Monty Python's Meaning Of Life*
A Fish Called Wanda*
(The first half of) Stripes
The Money Pit / Big
Natl' Lampoon's Vacation
(The first half of) Good Morning Vietnam
Sixteen Candles (not as good a movie as Breakfast Club, perhaps, but arguably funnier)
Better Off Dead / One Crazy Summer (these might as well be the same movie to me)
* I can't believe I forgot these two when I drew this list up. Sorry, boys!
** Princess Bride is one of my favorite movies, ever. It's just that I don't necessarily think of it as a comedy.
