He who approaches the bridge of death must answer me these questions three, and the other side he see.
~ The Bridge Keeper
What is your name? What is your quest? your favourite colour?
~ The Bridge Keeper's three questions.
~ The Bridge Keeper to those who approach him.

The Bridge Keeper is a supporting antagonist in the cult classic British comedy film, Monty Python and the Holy Grail. He watches over the Bridge of Death, which spans the Gorge of Eternal Peril.

He asks anyone who wishes to cross three questions. If they get one wrong, they are magically hurled into the gorge.

He often used clever tricks, such as asking Sir Lancelot simple questions, then adding more difficult ones for Sir Robin. He was apparently killed when King Arthur turned one of his questions back on him. He couldn't answer, and was hurled into the gorge. The said conversation goes like this:

Bridge Keeper: What is the air-speed velocity of an unladen swallow?
King Arthur: (confused) What do you mean? African or European swallow?
Bridge Keeper: I don't know that! No, WAI-AAAAUUUUGGGHHHH!
