Barbara Walters was on Larry King Live last night in support of her just-released memoir Audition (not that the book even needs much hyping; it sold an unprecedented a quarter-million copies in under a week). Perhaps it's the fatigue caused by the press tour, or maybe it's a newfound embrace of silliness now that she's spilled her guts into that memoir, but Babs is starting to act really strange. She pulled a gag last night by painting her fist to look like a face and talked to Larry in a weird voice. We're thinking that maybe this is an inside joke for the 75+ set. Clip above.
