... no "We've Got To Straighten Our Knees"?! What the serious buck, ad compilation people?!?

Both The Comedy Channel and HA! were kind of half-baked cable channels, HBO owned TCC and Viacom owned HA!
So at the same time TCC was showing the Higgins Boys & Gruber introducing the same clips of stand up comics and clips from comedy films, and reruns of what seemed like the shame handful of films (along with Rich Hall's Onion World and some cow-town UHF puppet show called MST3K), HA! specialized mostly in whatever sitcom reruns Nick at Nite wasn't showing yet, like "Rhoda", which was easy for them since they were owned by Viacom and they owned loads and loads of sitcoms. Still Comedy Channel made do with all of their HBO stand up footage and HBO/Warner movies, so in the early days of TCC there was a 1 in 5 chance you'd tune in and be treated to clips from Beetlejuice.

The Comedy Channel, was apparently, originally concieved as some sort of MTV for comedy showing nothing but clips of stand-ups and scenes from classic comedy films. During the late 80s some new cable networks attempted to emulate MTV and it's video-jockeys in a halfassed manner, they thought this sort of schedule-free "content soup" format was the hip new thing, all you had to do was show clips of things and have some wacky host or hosts introduce them! Fortunately, this trend didn't last too long.

I watched plenty of Comedy Channel in middle school, let me tell you.
