Here's a quote, it's a real toughy but definitely a classic  
X: Your majesty, the Globetrotters are ready.
Y:Let the peasants wait.  They will be rewarded by the opportunity to gaze upon the most beautiful woman in the land.
X: History has never known beauty such as yours.
Y: Sometime ago there was one more beautiful than I.
X: Not Snow White?
this from history of the world?
Not History of the World.  Man I can't believe my quote has some people stumped (of course maybe it's because nobody has actually seen the movie), some more random quotes from the same movie:
Girl:  Did the wicked queen send you to find me.
Man:  Lady, the wicked queen is trying to find me.
Girl:  What's your name?
Man:  Hubert "Geese" Ausbie of the famous Harlem Globetrotters.
Girl:  Oh sure, please mister I'm serious.
Man: I'm not jiving you honey, I'm one of the Globetrotters.
Man 1:  Excuse me there Li'l Miss, but how come your furniture is so small
Girl: Oh it isn't my furniture, this house is owned by the Seven Dwarfs, they're off in the hills digging for gold.
Man 1: The Seven Dwarfs?
Man 2: The Seven Dwarfs?
Man 3: Then you must be Snow White!
It's got to be from the Harlem Globetrotters cartoon.  Was that a movie too?
Eh, close enough.  It's from the 1980 movie, 
The Harlem Globetrotters Meet Snow White (seriously).  Edgar my man, you're confusing another classic of American cinema: 
The Harlem Globetrotters on Gilligan's Island.  That would probably be my first choice of a movie to quote, but I can't remember nor find any quotes or clips of it online, unlike this gem:
