With NBC's late night lineup in a state of transition right now, this is as good a time as any for this topic. Anyone else miss the use of fill-in hosts on late night talk shows? Johnny Carson was, of course, the primary adherent to this practice. By the early 80's, Johnny had settled on more or less permanent guest hosts (first Joan Rivers, then Garry Shandling, and eventually, Jay.) Before that, though, he used a pretty large group of subs, like Joey Bishop, Bill Cosby, Flip Wilson, Jimmy Dean, Jerry Lewis, David Letterman, and probably a whole bunch I don't remember. There were a few memorable guest host moments, too...Don Rickles breaking Johnny's cigarette case (which led to Johnny invading the set of Rickles' sitcom "CPO Sharkey"), Cosby getting annoyed with Gary Coleman and carrying him backstage, and a couple that I've only heard about. One involved McLean Stevenson royally pissing off Euell Gibbons (the Grape-Nuts natural food guru) by saying things like, "I've tried that stuff, and it's terrible!", and another was with Joe Garagiola hosting the night the Beatles made their only Tonight Show appearance, leading John Lennon to ask, "Where's Johnny?" So who were your fave Carson subs?
