No particular order:

King Pin
Monty Python and the Holy Grail
History of the World Part 1
Three Amigos
Vacation

And my Darkhorse favorite

Spies Like Us - growing up while the Cold War was still happenin. This was a funny once over on those Russian Commie Bastards Contained lots of immature comedy for an impressionable preteen. Hasn't aged well tho.
