A London commuter is coming home from work one evening on the tube, when he gets a sudden violent intestinal upset. He is stuck in a crowd, and can't move, and to cut a long story short, his trousers become extremely unfragrant. The panic-stricken guy comes out of the tube station, and sees salvation in the form of an outfitters. He dashes in, picks up a pair of trousers his size, bangs down several notes on the counter shouting "keep the change", and runs onto a carriage of his local train and straight into the toilets. When the train gets underway, he opens the window and throws the offending trousers out, heaving a big sigh of relief. He then reaches for the outfitters' bag, opens it and sees a ladies' pink cardigan.
She said "Sorry I didn't have time to finish it!"
