Free Beer & Hot Wings: Baseball Player Pranked Into Believing Teammate Was Deaf [Video]
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!
