A friend in the RASC [Royal Army Service Corps, now renamed as {wait for it!} the Royal Logistics Corps!!!] in 1951, told this as an error by a teacher who misheard a new pupil's name, Archibald Izal Benton-Brown, as Archibald Arsehole Been-Done Brown {"been" pronounced in old upper-class aphetic mode as "bin"}: & instructs him how to spell her mishearing of this, in rational terms, incredible name. Which makes a certain sense absent in most versions, while still retaining the hi-speed patter effect.
