I was in the cafe the other day, chatting away with some other drivers, when one of them told us that a few years ago his wife left had him after 20 years of marriage.   "Twenty years", I said, "How did you cope?" He replied, "The first five were the worst, but once I'd learnt to ignore her the last fifteen just flew by".

My wife said she was fed up with my continually joking around and that we should sit down together and chat about my behaviour.  It was then that I pulled the chair from beneath her.
