*Chris Rock did what he had to do this weekend when he cussed out a fan for $20,000 at an autism benefit event, “Night of Too Many Stars: An Overbooked Concert,” – Comedy Central’s annual benefit.

According to a gossip column, the comedian launched the “f” word to someone he didn’t even know, but it was all for the cause.

The event took place at NYC’s Beacon Theater on Saturday. During the event, Chris offered to call someone’s ex and curse him/her for dumping the person with the highest bid. A young woman named Desiree won the bid. She got on stage and asked Rock to curse out her ex-boyfriend named Jeff for posting pictures of himself and another woman after he and Desiree had been together for a year.

Jeff’s number was dialed and the call was put on speakerphone. For three minutes straight, Rock hurled four letter words at the ex.
