When I was a young lad and didn't really understand such things (it was the year before last!

), my parents' dog was on heat. I'd obviously got some of her scent on me because no sooner had I left the house than a Jack Russell came hurtling up to me, got hold of my right leg and started sh*gging it like crazy!
I didn't know what it was doing but I knew I wasn't enjoying it so I started swinging my leg about but the little f*cker wouldn't let go (pun intended)!
I smacked him against a wall a few times but that didn't put him off.
I reckon he was rehearsing for a place on Mastermind or something
(I've started, so I'll finish!) ...
I bashed him against the wall a couple more times, then he let out a little yelp, shuddered, and finally let go. He staggered off down the pavement with a satisfied smirk on his canine face ...
