Cosmo Kramer (Michael Richards)—Kramer is Jerry's "wacky neighbor". His trademarks include his humorous upright pompadour hairstyle, vintage clothing and his energetic sliding bursts through Jerry's apartment door. At times, he acts naive, dense, and almost child-like, yet randomly shows astonishing insight into human behavior. Indeed, his oddities aside, Kramer is often the only main character acting with any sort of apparent conscience, and is typically the only one to lobby for maintaining social decorum in order to appease acquaintances. Although he never holds a steady job, he often invents wacky schemes which usually work at first but eventually fail at the end. Among these are coffee table books about coffee tables (for which he appeared on Live with Regis and Kathie Lee), and a brassiere for men called the "Bro" (or Manssiere suggested by Frank Costanza).
