Farmer Joke

Two farmers were in the local pub one night. "Its a funny thing," one of them said. "But none o'my cows are giving milk right now." "I had that," said the other. "Oi gave em all castor oil." "Castor Oil you says? I'll give that a try then." About a week later the same two farmers met up again in the pub. "You know those cows I tole you about," the first farmer said. "The ones that weren't giving any milk?" asked the second. "Tha's right," said the first. "Oi gave em all castor oil like you tole me and within a couple of days they all upped and died." "Ar," said the second farmer. "So did mine."
