Federer's biggest rival scored an "interesting" win over him this past weekend at the Madrid Masters, proving once and for all that no matter how good you are at something, you can look silly.
It really is something to see: Federer launches a serve towards Rafael Nadal, he returns it, Federer tees up a forehand - and misses completely!
"Well, I've had more beautiful match points... I decided to take a chance, and it didn't pay off."
With the win, the Spaniard improved to 15-0 this season on clay and captured a record 18th Masters title - one more than Andre Agassi and two more than Federer.
