A woman brought two airplane tickets on Southwestern airline; one for her and one for her six-year-old son. This was his very first plane trip.

They were flying along when the little boy turned to his mother and said, "Mommy, if big elephants have little elephants, and big dogs have little dogs, do big airplanes have little airplanes?"

Not wanting to get into the subject of sex with her son, the woman was at a loss as to what to tell him. So, she simply instructed him to ask one of the stewardesses.

A little later, the boy grabbed hold of a stewardess who was passing by his seat. "Miss," he said, "If big elephants have little elephants; and big dogs have little dogs, do big airplanes have little airplanes?"

Looking suspiciously at the child's mother, the stewardess said, "I bet she told you to ask me that, didn't she?"

"Yes," the little boy replied, "But do they."

After giving the question a little thought, the stewaress responded, "No, honey, the big airplanes at Southwestern do not have little airplanes, because we always pull out on time."
