A quick look at our local phone book shows 'Universal Cars' and 'Universal Plumbing and Heating'. One imagines a couple of space-suited chaps setting off in their Universal Car to see to a dodgy boiler on Mars. (The 'Universal Cars' is actually a taxi service to and from airports, presumably only on Earth. And the 'Universal Plumbing' firm, despite its ambitious name, is based in School Lane, Little Melton, rather a disappointing address.)
