SIR - With regard to the postal service in Bradford, I have a brain teaser for your readers.

A man posts a birthday card in Bradford city centre on May 22, 2006. On the envelope is a first class stamp. The card has to reach its destination of Oakworth, by May 25, 2006. Does the card make it?

Answer: No, it didn't, and it still hasn't. And it's September now.

The only reason I can think of is that the Pony Express still operates in Bradford, and while making the trip, they were robbed by highwaymen.
