Excellent
I had a slight accident last year involving a conker and a schoolboy (cue for smutty innuendo

).
I was riding along quite slowly about to turn a sharp bend, and my front wheel went over a conker that was in the road. It can't have been completely in the centre of the tyre as the conker shot out of its shell . . . and hit a schoolboy in the balls.
He hit the pavement like a sack of spuds, so I stopped to make sure he was OK. He was with a group of mates who all thought it was hilarious
Unfortunately some plonker with a mobile must have misinterpreted what was happening, and before I knew it, there were 2 police cars and an ambulance in attendance
