Greg Behrendt -- the best-selling author of the book that spawned the catch phrase "He's just not that into you" -- takes the stage at the San Jose Improv theater to try his hand at stand-up comedy. A former rock musician who's now a father living in the suburbs, Behrendt laments his waning coolness in segments such as "My Sexy Faces," "Tattoos for Daddy," "Playmate Playdate," "Chain Wallet" and "I Don't Understand My Robe."
