Lol! Ok I'll explain,
A bunch of boffins, a Psychologist, a Mathmatician and an Economist, comissioned by British Gas (why I don't know!?), have come up with a formula that predicts Sod's Law or Murphy's Law to you yanks!
Sod's or Murphy's Law is also cited as;
"Anything that can go wrong, will!"
"Whatever can go wrong, will go wrong",
"Whatever can go wrong will go wrong, and at the worst possible time, in the worst possible way",
"If there's more than one possible outcome of a job or task, and one of those outcomes will result in disaster or an undesirable consequence, then somebody will do it that way".
The Formula being:
((U+C+I) x (10-S))/20 x A x 1/(1-sin(F/10))
U = Urgency, C = Complexity, I = Importance, S = Skill, A = Aggravation and F = Frequency.
Somehow these guys figured this out and applied a score of 1 to 9 to each factor and added 0.7 for aggravation and then worked out a overall Sod's Law rating of 0 to 10!
I shouldn't need to give you guys any examples of Sod's or Murphy's Law! But here's a couple of examples of Sod's Law that actually happened to me, seriously I'm not making these up!
- Two Powder Fire Extinguisher went off in the back of my old Vauxhall Combo van whilst I was driving and filled up the front cab of the van with powder in seconds, couldn't breathe or see and then drove into the back of a car at 30mph. Here's a pic of the aftermath. Taken just after the RAC turned up you just make out a fine coating of powder over the van!
- My dog ate my parrot! Thought it had flew out the window, but no as it turns out my dog had left a brown steamy present on the carpet for me one morning and on the top of it was, well it was the birds beak!
- I got a couple of hours off work one day to take my driving test, the time off was all organised in advance. Passed my driving test first time, that was on 06/06/06

, went back to work and then I got paid off.
- During a games day at my local airsoft site I got shot in the ear, shot in tooth, which broke my tooth, kept going and then got shot up the nose, not on my nose or on the bridge of my nose, no the BB went up my right nostril. And after all that I managed to sneak up on a few of my mates, got in close, got one of them and gave the other a huge fright which made him jerk back and fire his M4 at full auto at point blank range and now I have a BB lodged in my lower lip! Not bad for a day out.
Sorry to hijack this thread but you did want an explanation and by my reckoning Sod's Law is a major factor in my life, just gotta learn and remember this simple piece of advice,
DON'T PANIC!
