Some time ago I watched an episode of Saturday Night Live. Even then it was a distant rerun, from Jean Doumanian's ill-fated run. You could sort of tell things were going badly. The cast was kind of spotty, although the late Charles Rocket was always an underrated performer. Malcolm McDowell said in his monologue that he was only hosting to renew his work visa, and it was easy to believe him. The tone of the sketches was frequently off.
Doumanian did, however, get the Captain. That makes up for a lot.
Note that the "Fire! Fire! Fire!" thing was way before Beavis and Butthead.
