Dyan Cannon!
I think she was hilarious and likeable in a pathetic way... and before people start saying she was annoying, well, she was supposed to be whiney. I felt so bad for her character; it's a compelling performance that definitely didn't deserve the Razzie nomination she got. However, even though the Razzies sometimes get it right when they give it to talentless scumbags like Paris Hilton, they've nominated some great people, especially in the 80s (for instance, Stanley Kubrick was nominated as worst director for "The Shining" - WTF?).
