You would think big-time celebrities don't have any trouble finding people willing to be with them, and that may be true. It's finding people worth being with that can be more of a challenge. On 'Joan and Melissa: Joan Knows Best?' (Tue., 9PM ET on WE), Joan Rivers encountered a classic case of mismatched lovers.

She admitted that her date, Don, was a good-looking man, and she was certainly enjoying their dance lesson together. There was just one little problem.

"I'm having a lot of fun with him," she said. "Trouble is I think we're both looking for the same thing: A man to love us."

Later, in an attempted dip, the pair collapsed to the ground. "I don't think he'd ever been on top of a woman before," she quipped later.

While she may not have found Mr. Right, at least Rivers has found someone fun to hang out with. That could help her and daughter Melissa have some much-needed separate time occasionally.
