Novak Djokovic signs lots of autographs, especially at large tournaments. But signing a fan's leg? That was a first.
After The Joker took care of Austrian Bernard Tomic in straight sets at Wimbledon Friday, he was inundated with requests, including one from a man in the stands who handed Djokovic his prosthetic leg.
The world No. 1 obliged the man, and hoped it put a smile on his face .
"This gentleman gave me his artificial leg and I hope my signature will make him feel good," Djokovic told the BBC.
With the win Djokovic advanced to the fourth round of the tournament where he'll face South African player Kevin Anderson.
