Fry Clones

Multiple versions of Fry pop into existence, filling the screen with the same slack-jawed grin, the same enthusiasm for pizza and slacking, and the same complete lack of self-awareness about how strange it is that there are suddenly several of him. They mill about, bicker, and generally make Fry's obliviousness a crowd scene.

Billy West voices every single one, and the joke is entirely in his control: he keeps each clone recognizably Fry while letting small variations in cadence and dumbness multiply the character's comic essence rather than diluting it. It's a stunt that works because the writing trusts one performer to carry a room by himself.
