I actually love watching B movies for a laugh, so I've seen some terrible stuff. By far one of the most entertaining and ridonkulous ones was "The Thing With Two Heads". Its about an old racist white man whos dying so he orders a head transplant to be done. The only person they could find willing to do it was an innocent black man on death row. For some reason the process of head transplanting requires a layover period in which BOTH heads are attached. The black man wakes up, and , having control over the body escapes, dragging the bigot man along for a wild and stupidly hilarious ride. It includes all kinds of corny 70sness, THE longest lamest car chase I have EVER seen, and plus the white head serves almost no purpose for the rest of the story except saying the dumbest racist things he can think of. Oh and one random scene where a gorilla breaks free from a cage and tears up a corner store. Of course justice prevails in the end and the accused murderer finds a black doctor to remove the white head and rides off into the sunset singimg "Oh Happy Day" to the radio. Talk about a silly idea!
Goofiest anything I've seen isn't a movie. Panty and Stocking with Garterbelt. I sometimes worry about that show. XDD It blows Young Frankenstein (Mel Brooks) out of the friggin' water in goofiness. Just plain weirdness. Silliness!
