TV: Munch

Speaking of Richard Belzer, I wonder if he holds the record for playing the same character on the greatest number of different TV shows.

His Detective Munch first appeared as a regular character on Homicide. After that show ended, Belzer became a regular on Law & Order: Sports Utility Vehicle as Munch -- and how many characters have ever done that to begin with? Become regular characters on shows that were not spin-offs of their original shows?

But he's also guest-starred as Munch on The X-Files, the original Law & Order, and on the very short-lived The Beat. That's five shows on which Belzer has played the same character -- and only two of those shows are otherwise related to each other in any way (the two Law & Orders). Can anybody else match that?

Let me be more specific -- I'm talking prime-time shows only, here. If you counted cartoons, then Henry Winkler might hold the record, as he voiced the Fonzie character in two different cartoons (Fonz and the Happy Days Gang and the not-at-all awkwardly named The Mork & Mindy/Laverne & Shirley with the Fonz Show), in addition to Happy Days, Laverne & Shirley, Mork & Mindy, and Joanie Loves Chachi.

On the one hand, I genuinely want to know if I'm right about Belzer holding the record or not. On the other hand: wow, I gotta get a life.
