David is OK. I prefer Jay either, he seems more sweet on jokes, David seems like he means in his jokes, and sometimes it can be interpreted in a wrong way by the one he is interviewing, like Cher did once. She slapped him I guess!! !!
They were both on with Jay Leno this time last fall. I once read a transcript of a joke of his from a long time ago when Kournikova criticized their muscles. Jay said that they needed the muscles to lift all the trophys they were winning, unlike Kourny.
