This one is incredibly silly. It’s called “The Name Game”. Get two people on the phone (it works best with a guy and a gal) and only introduce them to the audience as “caller one and caller two”. Going back and forth, each gets five shots at guessing the other’s first name. First to do it wins your jackpot or prize. But if neither do it, the prize goes in the bundle and you come back again the next day at the same time with two fresh people. This will go on forever and you’ll never get a winner and that will be the allure.
