the Post Office had its Regulations, and so the chief postal inspector was brought before Postmaster Cowerby and asked why he had decided to risk destroying the whole universe in one go. According to Post Office legend, Mr. Rumbelow had replied: “Firstly, sir, I reasoned that if I destroyed the universe all in one go, no one would know; secondly, when I walloped the thing the first time, the wizards ran away, so I surmised that unless they has another universe to run to they weren’t really certain; and lastly, sir, the bloody thing was getting on my nerves. Never could stand machinery, sir.”
