I once did a poem in a folk club based on Sponnerisms

after a pre-amble explaining that Friar Tuck was a spoonerism and pausing just long enough to say

"I see you are all ahead of me ----- yes - as you spotted it is Fire Truck"

as I was into the next spoonerism a chuckle came too early, and a man explained he was still explaining the Friar Tuck joke to his wife - that got a better laugh.

Long may he continue to amuse us.
