Wristlo-Jackomater

A robot glimpsed in the crowded margins of New New York, the kind of oddly-named background face Futurama tosses off without explanation. Whatever its job or gripe, it exists mostly at the edges of a scene, adding to the show's sense that every extra has a whole daft life happening just off-camera.

The joke is almost entirely in the name — that clattering, portmanteau robot-suffix Futurama loves — and Tress MacNeille, one of the show's great utility voices, gives it just enough personality to land the gag and vanish. It works because the show trusts a single beat of specificity over any real development.
