A friend of mine had never heard of "TV Funhouse" despite being a huge animation fan. "TV Funhouse" (or its variations) originally appeared in such places as "The Dana Carvey Show" and its own short-lived cable show before it made a long-time home at "Saturday Night Live", actually being the funniest part of "SNL" for a number of years.
There are many classics over the years including "Steadman", "The Ex-Presidents" and "The Black Sabbath Show" among many others.
My favorite which I will link here is "Journey to the Disney Vault", which includes footage of "Song of the South" and Mickey Mouse ("You're supposed to be funny?").
