Movie: Monty Python and the Holy Grail (1974)
It's nearly impossible to pick one "best scene" in Monty Python and the Holy Grail, the flawlessly executed parody of King Arthur's tale from the iconic British comedy group Monty Python. But, if you'd put a gun to our heads, we'd have to go with the Black Knight sequence.
King Arthur (Graham Chapman) and his loyal sidekick Patsy (Terry Gilliam) come across a bridge that's being guarded by the aforementioned Black Knight (John Cleese). Arthur offers the knight a spot on the court of his Round Table, but the stubborn knight refuses, instead challenging Arthur to a sword fight. Which Arthur readily wins, chopping off all of the knight's limbs.
That doesn't stop the Black Knight from talking smack, though. When his left arm gets lopped off, he says, "'Tis but a scratch," and that he's "had worse." Next goes the right arm, to which the loser says, "It's just a flesh wound!" Before long, Arthur leaves the knight with only his left leg for an appendage, and asks the bullheaded chap if he's going to "bleed on me" to win.
As Arthur and Patsy make their triumphant exit, the Black Knight, who's just a stump with a head attached at this point, shouts, "Running away, eh? You yellow bastards! Come back here and take what's coming to ya! I'll bite your legs off!"
