His good friends,
Larry David and
Jerry Seinfeld, based the character of "Cosmo Kramer", played by
Michael Richards, on
Seinfeld (1989) around
Kenny Kramer. Kenny wanted to be the one to play himself on the show but Seinfeld wanted to get a professional
actor to play the part. Some things done by
Michael Richards's Kramer were actually done by
Kenny Kramer, such as the reality bus tour. In actual life, Kramer lived across the hall from
Larry David, not
Jerry Seinfeld.
