In an interview prior to his doubles exhibition at the SAP Open, John McEnroe reflected on his career and how he has maintained a high level of fitness throughout the years. He is a much more mellow guy at 53 years of age (well.....kind of) but since it is his special day, I think we should pay homage to the original 'Mr. Cranky Pants' and relive one of the most famous outbursts in tennis history. Happy Birthday! Enjoy!
