Wimbledon is the oldest tennis tournament in the world. The biggest names from the sport compete every year, and it’s a chance for diehard tennis fans to see the world’s top tennis stars compete in the most prestigious tournament.

On Wednesday, one fan was so happy for a chance to meet Rafael Nadal that he had the two-time Wimbledon champion sign something very personal for him.
 

Nadal was probably just expecting to sign some regular and oversized tennis balls and some shirts and hats, but he was caught off guard when a fan requested an autograph on his prosthetic leg.
 

This is definitely a lot weirder than a toaster, but according to Nadal he’s signed some stranger items over the years.
