This fist shaking lark

I've just realised that I've got a few posts on here that end with me shaking my fist in defiance. Let me explain. I believe this action has forced itself into my life, not by someone standing there and shaking their fist until I start doing it, but through the media of cartoons. I believe I've seen episodes of both King of the Hill and The Simpsons where characters have urged others to shake their fists like an old man after some local kids have just smashed his gnome.

For me the motion has several uses. Usually it's used to damn someone after they've either outwitted me or just plain been cheeky. It can be used towards myself when I've made a mistake, or to God when I think he's taking the piss....just in case he does exist. It can also be used to lord a victory over someone else. No doubt I'll find further uses for it, and damn you if you think I won't *shakes fist at the screen*
