Hi Pink Smartie, you reminded me of a train trip I made with my sister once from London to Cambridge during the commuter rush, I'd bought the Challenge Anneka (remember that programme) book of jokes and was reading them to my sister. They were really bad jokes and we'd had a G & T each and started laughing and eventually ended up helpless with laughter reading these jokes, the person next to us started laughing too and then the chap over the aisle, eventually everyone in the carriage was laughing helplessly - some didn't even know why - and when we got off everyone clapped and cheered and said it was the best trip they'd ever had!
