“Kook”.
O'Reilly gets more outrageously tabloid-ish, politically-illiterate and buffoonish every night. Beck is way, way too smart for him and O'R knows it, thus the insults.
Methinks the relationship will cool off when the "concerts" contract runs out and Beck finally goes on his own. He doesn't need the clown prince of Fox for ratings boosts any more. In fact, if time slots were reversed, Glenn would blow the Bloviator out of the ball park.
My personal opinion is that the two mutually despise each other.
I despise just one of them. See my tag line.
