Love may mean nothing in tennis, but off the courts, McEnroe’s love for animals means a lot to him. Recently, McEnroe, who has a mixed-breed pooch named Lulu, took a time-out from tennis to promote spaying and neutering in a new public service announcement (PSA) for PETA. In the lighthearted PSA, McEnroe is a good sport as he pokes fun at himself by unleashing one of his trademark tirades that is sure to raise a smile and raise awareness about animal overpopulation.
