Mad Dog 

A crazy old git that sometimes gets as mardy as his arse even if you haven't done anything wrong. It's a gamble wether you're gonna piss him off or not or vice versa.
It's also a McPorritt that can't find anything to do with his hair, needs to pull his trousers up sometimes and drive a little quicker now and again.
