I would have thrown tomatoes at her. Of course, I wouldn't be there in the first place.

NEW YORK (AP) - The most riveting moment of Barbra Streisand's Madison Square Garden concert was one of the only unscripted ones. Streisand endured jeers as she interjected a political skit into Monday night's show, exchanging zingers with a celebrity impersonator playing George Bush as a bumbling idiot. Though most of the crowd offered polite applause during the slightly humorous routine, it went on a bit too long, especially for those who just wanted to hear Streisand sing. "Come on, be polite!" the well-known liberal implored. But one heckler wouldn't let up. And finally, Streisand let him have it. "Shut the (expletive) up!" Streisand bellowed, drawing wild applause. "Shut up if you can't take a joke!" With that one F-word, the jeers ended. And the message was delivered - no one gets away with trying to upstage Barbra Streisand, especially not in her hometown.
