The Rev. William Archibald Spooner (1844-1930) was famously reputed to swap consonants in his speech (“The weight of rages will press hard upon the employer”).
His legend has grown so popular that today it’s hard to known which “spoonerisms” really happened. For instance, Spooner might really have asked, “Is the bean dizzy?”, but he almost certainly never said, “You have hissed all my mystery lectures and were caught fighting a liar in the quad. Having tasted two worms, you will leave by the next town drain.”
But we can be fairly certain that when he proposed a toast to “The Boar’s Head” (a pub), it was not a spoonerism.
He was a priest, after all.
