Bridge Keeper

The Bridge Keeper is a villain from the 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 killed when King Arthur turned one of his questions back on him. He couldn't answer, and was hurled int the gorge.
