TangoWhiskey I can fully sympathise there.
As a right arm bowler, I was once bowling left arm to try and give some runs away (don't you love Sunday beer matches!)
The batsman nails one straight back at me, testicle height, I cant get out the way and didn't get my hand there quick enough.
I did get a C&B to my name, but I also ended up on the floor unable to move for a while, then sat with an ice pack on my nadz for the next half hour, one of the most painful feelings ever!
Looking back I can laugh, but at the time it definitely wasn't funny (for me anyway, everyone else thought it was hilarious!)
