If there was ever a perfect candidate for a lesson in social media, it's the disgraced New York congressman. After a photo of a man's bulging crotch appeared on Weiner's Twitter feed, he claimed he was hacked. (Call it junk mail?) Weinergate ensued, forcing the politician and dad-to-be to finally come clean that the photo was, in fact, of him. Weiner resigned from his post, saddening late-light hosts and comics everywhere.
