Cosmo Kramer
Played by Michael Richards

His schemes were more hairbrained than Lucy Ricardo's or Ralph Kramden's. And he sure knew how to make an entrance.

Occupation: Kramer never seems to have had a real job, but he has been involved in many schemes; claims he worked in a bagel shop 10 years ago

Parents: Unknown

Signatures: Crashing into Jerry's apartment without knocking, eating Jerry's food without asking, giving his unsolicited opinion, twitching around and generally freaking out for no apparent reason

Notable quote: "A bra is for ladies. Meet the Bro."

GREAT MOMENTS

The butter shave: Kramer starts using butter from Jerry's kitchen instead of shaving cream; then he starts bathing in butter to soften his skin; by the end of the show, he has been sauteed.

The switch: We find out Kramer's first name, "Cosmo."
