Rear Admiral Tully Shelley, managing director of a company of oil refinery and construction engineers, designed a match striking machine as an April Fool's Day joke. He called it his "Yonghy Bonghy Bo" (an allusion to Edward Lear's poem, "The Courtship of the Yonghy-Bonghy-Bo"). However, the machine actually did work and could be used to light a cigarette.
