Two farmers were at the local cafe having their weekly coffee. One farmer
said, "I got a mule that has the fits. What did you do for your mule when he
had the fits?"

The other farmer said, "I gave him a mixture of turpentine and kerosene."

The next week they met again in the usual booth. "That was real good advice
you gave me", said the first farmer sarcastically. "I gave him the
turpentine/kerosene mixture and it killed him."

The other farmer said, "Yeah, it killed mine, too."
