A city man went to the countryside to buy a pig.
He approached a pig farmer and said,
Man:
“I’d like to buy a 25-pound pig.”
The farmer picked up the pig’s tail, put it in his mouth, and bobbed his head up and down. After a moment, he said,
Farmer:
“Sorry, this pig is too heavy. I’d say it’s about 30 pounds.”
The city man looked confused.
Man:
“That’s not how you weigh a pig!”
The farmer called his son over and asked him to check the pig’s weight.
The son picked up the pig’s tail, put it in his mouth, bobbed his head a few times, and announced,
Son:
“Yep, 30 pounds.”
The city man shook his head.
Man:
“You two have got to be joking!”
The farmer called to his son.
Farmer:
“Go get your mother. Tell her to come out and weigh the pig.”
The son went inside. A few minutes later, he came back.
Farmer:
“Well? What did your mother say?”
Son:
“Mom’s weighing the mailman.”
