Mischa Barton at the Sony Vaio and Windows Launch event at Gustavino's in New York (10/7)

Mischa Barton had quite the fun Halloween night: a guy threw a drink on her (always a dream of hers), she threw a drink on him (a nightmare for her to waste alcohol like that), and then she watched as her friends beat up the guy. Fun! A witness told Radar:

"I was standing beside this guy at the bar when Barton went past us carrying two drinks..."

Presumably both hers . . .

"The next thing I knew he threw his drink over her back and she turned around and asked him: 'Did you just throw a drink over me?' The man responded that the drink was in retaliation for Barton stepping on his shoe."

Barton returned to her table (supposedly after she gave the guy a taste of his own medicine and "threw one of her drinks" in his face) and told her friends of the incident. One especially incensed pal went up to the drink thrower. Within a few minutes one of her male friends came over to confront the guy and asked him to step-outside. Barton's friend left but then he kept coming back every few minutes to complain." Allegedly, things heated up from there and the two men ended up fighting one another on the dance floor before two bouncers came over and ejected the instigator from the club.

I'm not a doctor but I'm pretty sure it's not healthy to be drinking and getting into fights just three months after you were released from the mental hospital. I never thought I'd say this but Mischa needs to be more like Britney. After she was released from the mental hospital, Britney gave it a good six months until she got into her first bar brawl. And it wasn't even really her fault. Don't you hate it when the voices in your head start shit that you have to finish?
