If you are a true connoisseur of cringe, see if you can find "The Eiger Sanction" with Clint Eastwood and George Kennedy. There's a part in that flick where Clint Eastwood's character pretends to be a gay-coded deliveryman with a package of dental floss. "What am I gonna do with this boxth of floth?" Unforgettably bad but mostly unforgettable :)
