Children at Party

An unnamed cluster of kids voiced by Tress MacNeille pops up at a party in the Futurama world, background noise for whatever adults are actually being lampooned. They chatter, they whine, they exist for a beat of scale and absurdity before the scene moves on to its real target.

The joke is entirely in the craft: MacNeille pitches these throwaway voices with the same commitment she gives named characters, so a single line of party-kid chatter lands with a specificity that bigger shows wouldn't bother earning. It's a small proof of how densely Futurama built its world.
