What's The Dumbest Movie Ever Made?

Not "dumb" as in goofy and slapdash in a kind of likable-despite-itself way that at least manages to kill two hours. I mean "dumb" as in relentlessly, painfully, buzzsaw-to-the-brain inept and unwatchable, leaving you wonder who to sue to get those 120 minutes back.

I'll start with an example: Porky's Revenge. Any argument? No, I didn't think so.

Well, let me add some less obvious examples: Prozac Nation. The Happening. People I Know. Gigantic. Night of the Lepus. Duets. Revolution. A Countess From Hong Kong. Quintet. Fly Me To The Moon.

Got it? So what was your moviegoing bottom?
