This isn't really a hack (I wasn't that smart). My earliest memory of playing round with computers was at primary school when I was very young, it asked me to enter my name so I typed in 'poo'. I then showed my friend and he laughed and hit his fist onto the keyboard really hard and the computer froze with the word 'poo' frozen onto the screen.

I got into big trouble as the teachers thought I'd crashed the whole computer, they shouted at me pretty hard!

I still think it's quite funny to enter your name as 'poo'.
