There's a "Seinfeld" episode during which George and his fiance Susan were seen watching an episode of "Mad About You" on television.
But on a "Mad About You" episode, they reference Paul Buchman subletting his apartment to Kramer, and in another Mad About You episode, they show Paul meeting Jerry on a NYC street. Worlds collide.
Also, in another "Seinfeld" episode, Jerry goes on the Tonight Show with George Wendt and Corbin Bernsen, as the actors who played characters in "Cheers" and "L.A. Law" and not as Norm and Arnie, so those universes definitely do not overlap, which would have to mean that in the "Seinfeld" universe, "Frasier" *must* be a TV show.
Shame. Dr. Crane could have done a thing or two for George Costanza.
I don't think there's ever been any kind of Seinfeld/Friends crossover. I could never have seen him agreeing to it.
