Hysteria

For some reason, for about an hour this afternoon, I kept thinking about a joke. "I saw a man with a wooden leg, and a real foot".  (I think it was Steve Wright?)  I just couldn't help sniggering about it. Perhaps it was the stress we're all facing re next week; we're all slightly hysterical. It got a bit embarrassing. I'd be walking to the photocopier or something, trying to stifle a chuckle and at one point an almost tearful, full-blown roar. And then something went really wrong with next week's programme. That did the trick.
