Who can figure out network executives?
As Fonz & the Happy Days Gang began its second season, another branch of the Happy Days tree grew a branch of its own, as Laverne & Shirley were spun off into an animated series of their own, which saw the title characters (Penny Marshall & Cindy Williams) enlist in the Army. Curiously, Hanna-Barbera did the same thing with Popeye's girlfriend, Olive Oyl, and Alice the Goon over on CBS the same year, and that particular idea flopped harder than a stack of frozen flapjacks.
While Olive & Alice actually had a human CO (Jo Anne Worley, ex-Rowan & Martin's Laugh-In), Laverne & Shirley were stuck with, of all things, a talking pig, Sgt. Squealy (Ron Palillo, ex-Welcome Back, Kotter), who was always threatening to turn them in to his CO, Sgt. Turnbuckle. Seems Squealy was ten times more annoying than that other pint-size pest in the H-B zoo, Scrappy-Doo.
However, the girls' hitch in the Army lasted longer, because a 2nd season was ordered as a means of adding Fonzie (Henry Winkler) to the mix, after his cartoon had ended. Viewers were forced to assume that he, along with Richie & Ralph, had made it home. After all, his pet pooch, Mr. Cool (Frank Welker), was also brought along. You can pretty much guess how that went.
Anyway, here's the open, and the title card for the series premiere, "Invasion of the Booby Hatchers":
I wanted to give this a chance, but H-B counter-programmed itself, since Smurfs aired at the same hour on NBC. Enough said.
