So I was watching some comedic anime voiceovers (They usually put vine audio over the animation), specifically for the anime Hetalia. And the character that is France was yelling that at England (It's an anime where all the characters are personifications of countries :D).
Silly question I know, but whatever movie it comes from sounds interesting.

It's from Monty Python and the Holy Grail. You should watch it, Monty Python films are usually considered very funny.1
