The Deaf Mule

An Irishman named O'Leary, who loved to sing as he worked, bought a mule
to farm his garden. The mule worked well but was almost totally deaf.
So, when his owner yelled, "Whoa!", the animal often continued plowing.
Asked how the mule was working out, O'Leary shook his head. "There was a
time," he said, "when all the neighbors could here was me singing my
liltimg melodies." "Lately, I'm afraid, they've heard nothing but ....
my riled Irish whoa's!"
