A great comedian whose enduring gags were those pointing up unnoticed absurdities in ordinary life. My personal favourite, which I remember watching as a very small boy, was one about a sign he had seen saying "Are you Illiterate? If you have trouble reading and writing, contact this address!"

In memorium, I'll offer my own. On the back of a credit card I saw a small notice saying "If your card is lost or stolen phone 0898xxxxxxxx". Handy, I suppose, if you've just stolen one.
