Republican presidential candidate Michele Bachmann appeared on The Tonight Show Friday evening, trying to explain her husband's "pray the gay" comments and therapy on same sex marriage.

Host Jay Leno was perplexed by that phrase, seeking to find any understanding on it. "Well that whole 'pray the gay away, I don't get that,' Leno said.

Bachmann offered a peculiar reply. "Well see, when I heard that, I really thought it was like a mid-life crisis line," she said. "'Pray away the gray,' that's what I thought it was."

Sensing that Bachmann wouldn't budge on her feelings on gay marriage, Leno added: "I'm not going to change your mind on that one."
