John McEnroe Cake Swatting incident at Wimbledon

Mandela effect or Hidden History

When I was young I watched a lot of tennis, but the most memorable tennis moment of all time happened at court side at Wimbledon when John smashed a cake into crumbs with his racket during a changeover. It was replayed dozens, if not hundreds of times. I cannot find it. I have written to NBC, the Tennis Hall of Fame and even McEnroe himself and none of them have responded.Does anyone else remember this? Does anyone have it on video? If so please upload.
