A man decides he wants to have a pig roast, so he goes out to a pig farm
to buy one. He agrees on a per pound price with the farmer and then
begins to select a pig. "How about that one?"
"OK," replies the farmer. The farmer then picks up the pig, puts it`s
tail in his mouth, lets it hang from his mouth and then declares, "This
one weighs 74 pounds."
"That`s amazing," the man says, "Are you sure you can tell a pigs` weight
by using that method?"
"Yep, says the farmer, we`ve used this method in our family for
generations." To prove his accuracy, the farmer puts the pig on a scale
and it weighs exactly 74 pounds.
"My son can do it, too," boasts the farmer. Sure enough, the farmer's son
comes over, puts another pigs` tail in his mouth, lets it hang and then
says, "This one weighs 83 pounds." The farmer then confirms his sons`
accuracy with the scale.
"My wife can do it, too," says the farmer. "Son, go get your mother."
The boy runs off to the house and returns a few minutes later. "Mom can`t
come out right now," says the son. "She`s busy weighing the mailman."
