Cosmo Kramer

Cosmo Kramer is a character on the American television sitcom Seinfeld (1989–1998), played by Michael Richards. Kramer is the neighbor of main character Jerry Seinfeld. He lives at 129 West 81st Street, New York City, Apartment 5B. Of the series' four central characters, only Kramer has no visible means of support; what few jobs he holds seem to be nothing more than larks. His trademark include his humorous upright bouffant hairstyle and vintage wardrobe, the combination of which led to his categorization as a 'hipster doofus'; his violent bursts through Jerry's apartment door; and his penchant for nonsensical, percussive bursts of noise to indicate skepticism, agreement, annoyance, and a variety of other inexplicable responses.
