http://sportsillustrated.cnn.com/2006/writers/jon_wertheim/07/17/moments/index.html Hard to believe McEnroe, Nastase or Tarango didn't provide us with one. When McEnroe and Nastase met in the 1979 US Open, they spent the majority of the time disputing calls and abusing officials. So much so that Nastase was defaulted. The chair was replaced by the referee and Nastase was reinstated. Or at 1995 Wimbledon, when Tarango walked off the court after a barrage of disputes with the chair, then his wife ambushed the umpire after the match, slapping him in the face. Or the 1999 RG final between Hingis and Graff, when Hingis crossed over to Graff's side of the court to point to the mark. Ultimately, she was docked two points. Then she started serving underarm! After the match ended, Hingis burst into tears and ran off the court.
