Some I haven’t seen, but:
Animal House: Fat, drunk and stupid is no way to go through life, son.
Blues Brothers: We’re on a mission from God.
Blazing Saddles : But I shoot with this hand.
Young Frankenstein: Hump? What hump?
And my favorite Carol Burnett is the parody of Gone With the Wind and the famous drapery dress complete with drapery rod. When asked by Harvey Korean as Rhett Butler where she got the dress: Oh I saw it in a window...
I forgot about Animal House. Dean Wormer gets a whole chapter of classic quotes in that one.
Another brilliant one for quotes that stand the test of time is The Muppet Movie. Just rattle off a list of the human actors with roles in that movie and you can fill an entire block of the Hollywood Walk of Fame with them.
