Television viewers are familiar with "vanity cards," the industry term for images crediting a production company at a show's end. But the cards at two CBS sitcoms are different: Producer Chuck Lorre uses the instant of screen time for a changing public diary, the Wall Street Journal reports. Impossible to read at first, they become legible when paused on a digital recorder.
The installments—following Two and a Half Men and The Big Bang Theory—have become some of the most talked-about writing in Hollywood. Over 200 cards have ranged from a letter to his late father to gossip about network execs. CBS, while indulgent, has had to censor a couple of questionable entries. "I've always had the character flaw of wanting to bite the hand that feeds," Lorre said.
