Michael Richards
Michael Richards achieved the dream of many actors: he created a timeless character who ended up so universally beloved, so undeniably unique, that no one could imagine another actor in that part. As Cosmo Kramer, the gangly, perpetually amped, mooch of a neighbor to stand-up Jerry Seinfeld on the legendary sitcom "Seinfeld" (NBC, 1990-98), he was an indelible, always hilarious presence.
