Worst attempt at belly-dancing ever caught on film?

Based on the setting and the costumes, I have to assume that the women dancing for Raymond Massey, Ray Collins, Kathryn Grayson, and what's-his-name (the cad from The Best Years of Our Lives) were supposed to be belly dancing. If I'm correct in my assumption, then that has to be the worst approximation of belly-dancing I've ever seen in a movie. It was so bad it's hilarious.
