14. John McEnroe Goes Bananas
John McEnroe led Mikael Pernfors in sets, 2-1, in the fourth round of the 1990 Australian Open when he earned his third code violation for an automatic ejection, the first ejection for misconduct at a Grand Slam since 1967. McEnroe earned violations for intimidating a lineswoman, smashing his racket, and cursing at the umpire.
