'Good Show!'

A minor voice in the Futurama world, 'Good Show!' turns up as a broadcaster-type figure whose whole personality is compressed into hearty, old-fashioned enthusiasm. He narrates or reacts to events with the clipped, cheerful bluster of a vintage radio announcer, existing mostly to punctuate a scene with unearned delight.

The joke is entirely in the delivery: Maurice LaMarche, a voice actor built for booming pastiche, drops in a plummy, theatrical exclamation and vanishes. It works because Futurama trusts a single well-aimed vocal caricature to land a laugh without needing a name, a face, or a single line of backstory.
