There is a joke doing the rounds in Yorkshire. It recounts how an American visitor to Europe finds a phone in the Sistine Chapel that charges £10,000 ($14,000) per call. The priest tells him that it is a hotline to heaven and offers the chance to talk to God himself.

In every country he visits he discovers the same phone in each church with the same fee until he arrives in Sheffield where the call charge is just 20p. “Why is it so cheap?” he asks the priest. “You’re in Yorkshire now, son. It’s a local call,” he replies.
