Heyyy, It's The King! was a component of NBC's 1977 anthology series, C. B. Bears, which we discussed a few days ago. The King (Len Weinrib) was clearly modeled after Fonzie (Henry Winkler) from ABC's iconic Happy Days, but the rest of his crew weren't exactly on a par with Richie Cunningham and his buds from 50's Milwaukee. Of course, as we noted before, Fonzie would become a cartoon star himself in 1980.
Edit: 11/20/12: Due to circumstances beyond my control, the video for the episode, "The Blue Kangaroo", was pulled from YouTube. If it becomes available again, I'll get it back up. Sorry for the inconvienence.
