Imus was the dirty old perv that suggested the lap-sitting. Chris was just being honest. As for Sarah being “hot”, at the time she was hot politically, hot ratings-wise and hot visually. You can ascribe the meaning of the word any of the three ways and it still works.
I don’t doubt that there was some horseplay behind the scenes. There’s a difference between sexual bantering and clearly unwelcome line-crossing. I’m sure the women at FNC don’t behave as prudes. Offices learn quickly which women love the verbal sparring and which ones are offended by it.
Remember when Huckabee tattled on the foul mouthed women of FOX?
