The term Spoonerisms
originates from the Reverend Spooner, who is well known in England because of a speech problem he is supposed to have had; it is said that he used to mix up the first couple of letters of words, sometimes creating strange sentences
. One of the most famous spoonerisms
attributed to him is when he told a student off because he had 'hissed the mystery lectures' when he meant to say 'missed the history lectures'.
