Big plane, little plane
One day a curious little boy went to his mom and said “Mommy mommy, I’ve noticed that big dogs have litlle dogs and big cats have little cats, so how come big planes don’t have little planes?”
The mother looked at her boy and said, “I don’t know, ask your father.” So the boy goes and finds his dad.
“Daddy, Daddy!” he yelled. “Why do big dogs have little dogs and big cats have little cats, but big planes don’t have little planes?”
“Maybe you should ask the pilot tomorrow when we go on our trip,” replied the confused dad.
So the next day the boy gets on the plane and runs right up to the cockpit and says to the pilot, “Mr pilot sir, I’ve noticed that big dogs have little dogs and big cats have little cats, so how come big planes don’t have little planes?”
The perplexed pilot thought for a moment and said, “Well son, we’re T.W.A., and we pull out in time.”
