Breaking Bad signed off for good a little more than six months ago, but Walter White is still out there. What has he been up to? Helping a high school student ask a girl to prom. "If you don't go to the prom with Stefan, then maybe your best course of action would be to tread lightly," says Bryan Cranston in a "promposal" video that went viral. Cranston was signing autographs after a performance of a Broadway production of All the Way when Stefan Montana approached him asking if he would help Montana ask a girl named Maddie to prom.
