Well I've posted so many quality jokes in this thread, Doug (count 'em!), that I feel I might be permitted a slight, benign diversion in order to address Mrrzy's excellent though off-topic point about football. I can only conclude from your curmudgeonly intervention that you must be a Man U fan. Very sad.

And that last joke of yours is so old that I'm guessing that it was first told to Methuselah by Noah...
