Those who attended Tuesday's Washington Kastles match got much more than they paid for. John McEnroe, formerly the world's top tennis player, served up some swear words, racket throwing and general rowdy behavior as he played against the Kastles in the World TeamTennis match for the New York Buzz.

Coming onto the court with a wooden racket (which looked like "something from Victorian days," a spy reports), McEnroe showcased a solid serve, but it all went downhill from there.

At one point, McEnroe stopped the match to walk over to a woman in the stands and yell at her. He also received a warning from the head umpire for cussing at a section of booing fans. While his abysmal performance could have made for one awkward tennis match, we hear that the audience was mostly laughing. The Kastles won 22-16.

Spotted in the stands: National Economic Council head Larry Summers, wearing a suit, and host of "Fox News Sunday," Chris Wallace.
