“In the cramped confines of the toilet I had trouble getting out of my wet trousers, which clung to my legs like a drowning man. The new ones were quite complicated too in that they had more legs than a spider; either that or they didn't have enough legs to get mine into. The numbers failed to add up. Always there was one trouser leg too many or one of my legs was left over. From the outside it may have looked like a simple toilet, but once you were locked in here the most basic rules of arithmetic no longer held true.”
