Have you ever watched Shock Corridor? I tried watching it recently, and couldn't quite get through it. But this dance scene made me cackle. If you don't want to watch the entire video, the most hilarious parts are the intro and at about the 2:00 mark.
To be fair, Lady de Shock Corridor looks better, sings better, and dances better than I ever will, but I still find her dancing rather hilarious!
Have you ever tried to dance in a sultry fashion? I have to admit that I am NOT good at such things and just end up laughing. Chalk me up to a sexy fail. The boyfriend asks me to to give him a little dance every now and again, but BLEH. So I turned the tables on him and asked him to give ME a dance instead. He eventially ponied up and gave me a sort of striptease dance, and it was, well, entertaining. LOL.
If you are looking for more bad dancing, here is one more cringeworthy video. Enjoy.
