Barack Obama's Head

Preserved in a jar alongside the other great heads of history, this disembodied relic of the 44th President pops up as one more sight gag in the museum of Futurama's future, dispensing whatever wry or dignified remark the moment calls for. He exists to be glimpsed, to be recognized, and to make the joke land before the scene moves on.

The bit works because Futurama commits so completely to the absurd premise that celebrity heads in jars are just furniture in this world, and Phil LaMarr's vocal precision sells the cameo instantly — a couple of lines, the right cadence, and the joke is complete without ever overstaying its welcome.
