A veterinarian prescribed three huge pills to be given to a sick
mule. "How do I get him to take the pills?" the farmer asked.
"It's quite simple," replied the vet. "Just insert the pill into a pipe. Put the pipe in the mule's mouth and blow on the other end. He will swallow the pill without realizing it."
The next day the farmer returned, looking sickly.
"You look awful!" said the doctor. "What happened?"
The farmer explained, "He blew first."
