Bottomless Boy

Bottomless Boy is a passing figure in Futurama's crowded future — the kind of one-off gag character the show tosses off in a single scene, defined entirely by the sight gag his name promises. He appears, does the joke, and moves on without ceremony.

The pleasure here is Phil LaMarr's range rather than the character's depth: an actor best known for meatier recurring voices tossing off a throwaway sight gag with total commitment. It's a small joke, but it lands because nobody involved is winking at how small it is.
