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 :)
That's because Deckard is lying to her (poorly). Remember, he's not that good of a detective. They use him because he's willing to do dirty work and is expendable.
I have to make an excuse to get up though when Harrison Ford tries to play a nerdy fan in the Zhora character's dressing room. So bad.
