I remember hearing that on Imus' show.About 10 seconds after having started a conversation with Gregory,Imus asked "are you drunk?"...and all Gregory could do was giggle like a schoolgirl.
Mind you,this happened at about 7AM (Eastern).
Imus asks that of everyone who says something he doesn't like. It doesn't mean anything.
Except, of course, that he's talking to an idiot, and anyone talking to Gregory can say the same thing.
