Worst concept ever?
Quite possibly. Check out Hanna-Barbera TV STARS #2 (October 1978, Marvel), which cover-features the C.B. Bears.
You remember C.B. radios, right? Sure. It was a big deal back in the '70s. You could actually get a Citizen's Band Radio in your car and TALK to other motorists around you... long-haul truckers used them, and there was the weird notion that "truck drivers are America's last cowboys" that surfaced back then for some unknown reason. Ah yes, the noble Trucker. Ahem. Anyway. So here we have the C.B. Bears: Bump (who mysteriously wears a garbage can lid as a hat), Boogie, and Hustle, named for three "Disco" dance styles that still make me shudder as I remember my PARENTS taking lessons to learn them all. (Do NOT ask me about watching my Mom and Dad do the "Dirty Bump"... those memories still keep me awake nights.) Written by Mark Evanier (!) , this poor thing was dated before the ink was dry. Wotta hoot! And I have absolutely NO memory of that television cartoon... wonder if there was any merchandising? Garbage Can Lid Hats, perhaps?
