These are shows I watched in the 1980s and early 90s, about which I feel nostalgic, but which don't quite fit into any of the other categories listed above. Which means the shows on this page can be various different genres. (This includes sketch comedy and stand-up comedy, which you might expect to be included under "comedy," but that page is just for sitcoms.)

Carol & Company
CBS Summer Playhouse
Donahue
Jack Horkheimer: Star Hustler
Just for Laughs
The Kids in the Hall
Lorne Greene's New Wilderness
The Midnight Hour
The Nature of Things
Saturday Night Live (I feel nostalgic for maybe the first few years that I watched, which started sometime around season 15)
The SFM Holiday Network
The Smothers Brothers Comedy Hour
Switchback
Video Hits

Other stuff:

other game shows (a few of the shows on that page are nostalgic simply because I was young when I saw them. Others are too recent-and of too little interest-to be nostalgic to me at all)
other sketch shows (a couple of shows that are mildly nostalgic just because they were on during the time period that's nostalgic to me)
