i saw a horrendous rugby injury. in a sydney grade match a couple of years ago, a maul or ruck (i don't know the difference) collapsed and one of the players stayed down injured. he had dislocated his hip. nasty.
anyway, some tool in the crowd proclaimed that he is a doctor, and ran on to the field to help the injured player. doc did the count, whacked the leg back into teh socket, and the player let out the most harrowing scream and passed out.
dickhead doc didn't check to make sure that the player's RIGHT NUT WASN'T IN THE WAY!!
he had completely crushed his testicle.
