So I live in London and I'm catching the tube (underground train) home tonight. If you don't know London's tube, there's a row of seats along each side of the wall. I sat on one end of an empty row and there was a homeless guy sitting down the other end. He stank but I didn't pay too much attention to him, I was busy reading emails. Then we got stuck at one of the stops forever and I thought 'what is going on' then everyone started moving from the end of the carriage away from the homeless guy. Then two train conductor's got on board and told the homeless man to get off the train. As he got up I saw his scraped bum cheeks. He was sitting on the train with his penis out! I can't believe I didn't notice.
Could have been worse, after he got off someone sat where he had been sitting. I'm never sitting down on the tube again.
