I Misplaced My Watch At A Disco

So I tried to find it.

I saw it on the dancefloor, being stood on by a guy. That's when I noticed that he was trying to grope her and she obviously wasn't enjoying it.

I walked up to him, tapped him on the back and delivered a swift kick to his balls. He fell over, moaning in pain.

The girl, looking rather relieved, asks why I did it.

I picked up my watch, slipped it on and replied "No-one does that to a girl. Not on my watch."
