Analysis of information sources in references of the Wikipedia article "Spoonerism" in English language version.
In 1879 it was a favourite Oxford anecdote that Spooner from the pulpit gave out the first line of a well-known hymn as 'Kinkering Kongs their titles take.' [...] The anecdote is well enough authenticated, but according to most people who knew Spooner well that was the only "Spoonerism" he ever made – the essence of a "Spoonerism" being, of course, lack of intent, – though later when, thanks to indefatigable undergraduate and alas! graduates and dignified Fellows of colleges, the legends had become legion, he often used deliberately to 'indulge in metathesis,' to live up to his reputation.
