What is the hardest substance known to man?
Buck Shelford, former All-Black who, in his second test match against France, was trapped in a ruck. He lost four teeth and was knocked unconscious in the famous ‘Battle of Nantes’, but that was the least of his worries. A wayward boot found his groin, ripped open his scrotum (every boy following just winced and bit his lip) and pulled out one of his man-plums. Any normal man would be excused for crying, but no, Buck Shelford walked off the pitch, asked the physio politely to fix him up, then lay on the sideline while his testicles were returned to their normal position and stitched back up.
Diamonds are for girls.
