If Olbermann and I were to meet, I'd shake his hand and we'd discuss SportsCenter and Rita Cosby. I suspect we'd get along famously. I'm a liberal, after all.
If Bill O'Reilly and I were to meet, I call him on his BS, he'd end up trying to physically attack me (or sexually assault me) and I'd have to restrain him and accidentally knee him in the johnson repeatedly. Then I'd kick Ann Coulter in the johnson. For good measure.
