The guy may be the smartest guy on the planet, but he's a terrible host. He's rigid and calculated. I think he may have a mean streak too. Someone answers "Santa Claus," and he says, "Can you be more specific?" It's 'store' Santa Claus. I don't think he likes contestants to appear too smart. He seems uncomfortable when he interviews the contestants. His fall back line is, "I love it." I thought the lady who hosted for a little while was great. Her name was Mayim Bialik.
