Spoonerisms are named after the Reverend William A. Spooner (1844–1930), an English clergyman who uttered them frequently and apparently involuntarily and are the amusing result of the transpositions of sounds in a pair of words or phrases:
He referred to Queen Victoria as "our queer old dean."
"We all know what it is to have a half-warmed fish inside us."
"Is the bean dizzy?"
"When the boys come back from France, we'll have the hags flung out"
"The Lord is a shoving leopard,"
"It is kisstomary to cuss the bride,"
"Mardon me padam, this pie is occupewed. Can I sew you to another sheet?."
"You have hissed my mystery lectures; you have tasted the whole worm."
A couple of other funny ones I found:
Hollow your fart
A lack of pies
Enron: what a crunch of books.
We have a plaster man
you have mad banners
Candle with hair!
Go shake a tower
Tease my ears
