Spaw (don't know if you're joking, or not, but in case anyone else is wondering the same thing)--

"Doctor Who" is the longest running science fiction series. It ran from 1963 to 1989 with only one hiatus before it was cancelled. But it continued non-stop in the form of novels, comic books, audio dramas and Internet films.

Then, it was brought back to television in 2005. The main character (Known only as The Doctor) is an alien who travels through space and time meddling in history and making despots angry.

The alien has a nifty trick: whenever his body has a near fatal accident or illness, its cells and genes rearrange themselves, and he gets a totally new body.   That way, the show doesn't have to be cancelled when the lead actor wants to retire.

I've been a fan of the show since 1980
