Farmers Paddy and Mick would meet every month at the local fair to catch up. This particular month they sat and chatted over a beer.
“Tell me Mick,” said Paddy. “What did you give your mule when he had colic?”
“Turpentine,” answered Mick.
A few months later they met again at the next fair. Over another beer, Paddy asked Mick: “What did you say you gave your mule when he had colic?”
“Turpentine,” answered Mick.
“Well, I gave my mule turpentine, and he died,” said Paddy.
“That’s strange,” said Mick, “so did mine.”
