NEW YORK — Comedians are used to hecklers — but not Barbra Streisand, who swore at a guy who didn't like the President Bush impersonator she brought out for a sketch during her concert at New York City's Madison Square Garden. A few people in the crowd jeered at the skit — which portrayed the president as a bumbling idiot — and told Streisand to stick to singing. The well-known liberal told them, "Come on, be polite." But one heckler wouldn't let up and Streisand let him have it. Streisand later apologized to the audience... and delivered a message of tolerance. ...Streisand pointed out that "the artist's role is to disturb." Streisand has recently return to touring after a 12-year absence. Full story here: http://www.foxnews.com/story/0,2933,219244,00.html Guess Babs got a little hot under the collar?
