This prank is one of the best ongoing pranks anyone has ever taken part in.

The El Paso Chihuahuas' Triple A baseball team decided to convince one of their players, Jeff Francoeur, that another player on the team was deaf -- for a whole month. And he totally fell for it and had no idea he was being pranked.

It's a bit of a lengthy video, but still worth the watch. These guys are geniuses!
