I want to keep this as a seperate thread from the on-off episodes thread.

What are some instances where a character – or entire cast – from one TV show guest starred on another? For instance, on The Single Guy, the main character became friends with Ross (from Friends). (They both suspected the other of being gay.)

The Law and Order shows would cross over. I remember seeing Jerry Orback on SVU and there were other characters as well.

The Critic Jay Sherman on the Simpsons.

Fran Drescher & Ray Romano went to the same high school, and he appeared on her show.

3rd Rock from the Sun had an episode with Harry (French Stewart) being the head of Saturday Night Live (In one of the best guest shots ever, they also had Dennis Rodman starring as a fellow space alien)

Early in the series, Ray Romano and sometimes his mother made appearances on King of Queens. Memories iffy as to how many times but at least one episode centered around Ray and Doug spending the day together playing golf.

In one episode of _St. Elsewhere_, some of the doctors went to the bar from _Cheers_.

Several of the characters from _Cheers_ guest starred on some episodes of _Frasier_

_The Simpsons_ also has had guest stars from _Cheers_ and _The X-Files_ (and probably others shows, too).

There was an epispode of _Futurama_ featuring several characters from the original _Star Trek_.

- There were Friends/Mad About You/Seinfeld connections which implied a shared universe. (and by way of the OP, this would include the Single Guy)

- Ray Romano guest stars on King of Queens if I remember correctly.

- Magnum PI and Murder She Wrote crossed over.

\*Cheers and Wings (and naturally, Frasier) shared a universe.

Mr. Carlin (From the Bob Newhart Show) played a screwed up psychology patient on Newhart. (“I had to undo years of damage done to him by some quack in Chicago.”)

The character of John Munch from _Homicide: Life on the Streets_ not only guested on the original _Law and Order_, but crossed over completely to the _Law and Order: SVU_ series. He has also been in an episode of _The Simpsons_ (voice only, duh) , _The X-Files_, _The Beat_, the short-lived _Law and Order: Trial by Jury_, and _Arrested Development_.

He’s the most crossed-over character in TV history.
