If your local NBC station is carrying reruns of old Saturday Night Live episodes [in their entirety] at 1 am or later on Sunday morning, you might want to watch this weekend's edition.
It's Steve Martin's first appearance as guest host, from Oct. 23, 1976. A sketch during the first half hour, following Steve's monologue, is the classic Jeopardy! 1999, with Steve as "Art F114", Dan Aykroyd as "Danny M125", Laraine Newman as "Laraine A270", Chevy Chase as "Lee P413" [all of them sporting silver afros and Star Trek-type clothes], and Don Pardo as himself.
The original J! had already been off the air for over 1½ years at that time, so no one, not even Don Pardo himself, would have thought Jeopardy! would be on again in 1999.
