Field Trip

One day, a class of third graders from the city was
taking a field trip to the country to visit a small
farm. The kids were amazed to see all the different
kinds of animals on the farm. So the farmer asks one
little girl, "What's the difference between a rooster
and a hen?"

"The hen lays eggs." replied the little girl.

"Very good!" said the farmer. Then the farmer asked
another little girl, "What's the difference between a
duck and a turkey?"

"Well," replied the little girl. "Turkeys can't swim
and turkeys are what we have on Thanksgiving Day."

"Very good!" exclaimed the farmer. Then he asks little
Johnny, "Do you know the difference between a bull and
a cow?"

"Yes, I do" replied little Johnny from the city. "Bulls
smile when you milk them."
