Archibald Spooner's Cloak

Origin
William Archibald Spooner (22 July 1844 – 29 August 1930) was a famous Oxford don whose name is given to the linguistic phenomenon of spoonerism.

A spoonerism is an error in speech or deliberate play on words in which corresponding consonants, vowels, or morphemes are switched between two words in a phrase,for example saying "The Lord is a shoving leopard." instead of "The Lord is a loving shepherd." While spoonerisms are commonly heard as slips of the tongue resulting from unintentionally getting one's words in a tangle, they can also be used intentionally as a play on words.
