Babs Goes Bats

Using the "F" word against a fan while engaging in an anti-Bush skit:

There was Streisand, enduring a smattering of very loud jeers as she and "George Bush" - a celebrity impersonator - muddled through a skit that portrayed the president as a bumbling idiot.
Though most of the crowd offered polite applause during the slightly humorous routine, it got a bit too long, especially for a few in the audience who just wanted to hear Streisand sing like she had been doing for the past hour.
"Come on, be polite!" the well-known liberal implored during the sketch as she and "Bush" exchanged zingers. 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!"

Sorry Babs, no one's laughing at your failing talent!
