Henry Kissinger's Head

One of the many disembodied heads-in-jars populating Futurama's future, Henry Kissinger's Head turns up as a background fixture of New New York society — a relic of 20th-century politics bobbing along in his tank, occasionally offering officious, self-important commentary as if he still wielded real influence.

The gag depends entirely on deadpan absurdity: a former Secretary of State reduced to a jar, still projecting gravity and self-regard. John DiMaggio's gruff, clipped delivery treats every pronouncement as weighty statecraft, which is precisely what makes the joke land — the show never explains it, just lets him bob past.
