What not to say

I played 5-a-side football this evening with my cousin Raphe and some of his mates. Towards the end of the match one guy caught the full force of the football in the testicles. It had him on his knees for a couple of minutes and he was still holding his genitals tenderly as the whistle blew for final time. We all shook hands and as I approached him to shake his hand I almost said 'How are your balls mate?' but stopped myself just in time. I didn't want him to take it the wrong way and follow me into the showers!
