25. Christopher Walken as Captain Koons, Pulp Fiction (1994)
Captain Koons only appears in one scene of Pulp Fiction, but it's a damn memorable one. It's all thanks to his hilariously disturbing monologue to a young Butch Coolidge about the history of the little man's father's gold watch, his de facto birthright. For the two minutes we're with Koons, all he does is talk, but his casually harrowing tale of harboring a whole timepiece up his ass while imprisoned in a Vietnamese POW camp gives him all the credit he needs to contend with the rest of the characters on this list.
