Really funny jokes-Turpentine

Paddy and Mick, both farmers, met one day at a Kilkenny fair.
"Tell me," said Paddy, "what did you give your mule when he had colic?"
"Turpentine," said Mick.
A few months later they met again.
"What did you say you gave your mule when he had colic?" asked Paddy.
"Turpentine," said Mick.
"Well, I gave my mule turpentine, and he died," said Paddy.
"That's strange," said Dave, "so did mine."
