In an interview with Howard Stern, Seinfeld revealed that he "worshiped" Andy Kaufman so much that he would travel into the city just to watch Kaufman perform. When Stern stated that Kaufman would've fit in well with the "Seinfeld" cast, he replied, "Michael Richards is one of those parts, you could never cast somebody else. But now that you mention it, Andy could've pulled off Kramer."
