Cybill with an "S".

This is the episode with Wendie Malick, who plays Ira's girlfriend with the spontaneous different personalities, that seem to come out whenever water is running. But, I wished they had explained the reason for this. I know this being a half hour show, they really couldn't delve into why she only does it at that time, like, for instance did somebody try to drown her when she was very young, her mother maybe?
