Joy Behar's new television show, The Joy Behar Show, airs tonight for the first time on HLN (formerly CNN Headline News). When we stopped by the launch party for the program last week, we asked guest Joan Rivers who would win in a fight between the two comediennes. "I would," Rivers told us. "There's no question. With one hand tied behind my back." See our Party Lines slideshow for more. Related: Joy Behar's Big Break
