I heard this yesterday and it had me laughing. Jackie Mason, Borscht Belt comic and apparent Republican, has written a book entitled "Schmucks" which he went on The Young Turks to publicize. When asked to name a political schmuck in the book, Jackie hems a bit and then says "Al Gore" and questions why Al Gore thinks he's such a expert on global warming. The conversation devolves from there.
Audio available at The Young Turks (click on the picture of Jackie). Go take a listen to the second guest in TYT history to hang up during an interview.
