Jerry Seinfeld's The Marriage Ref has been on television for two weeks and America still does not know who Tom Papa is. But instead of giving Tom and Jerry the benefit of the doubt on their unfunny NBC venture, viewers are tuning out. Last night, the series plummeted just over 20% in ratings despite a star-studded panel including Madonna and Ricky Gervais. The third celebrity panelist, Larry David, was so disappointed with the experience that he even commented mid-show, "This is easily the most uncomfortable hour I've ever spent in my life." [THR]
