A mother and her very young son were flying Westjet Airlines from Ottawa to Calgary. The little boy (who had been looking out his window) turned to his mother and asked, "If big dogs have baby dogs, and big cats have baby cats, why don't big airplanes have baby airplanes?"
The mother (who couldn't think of an answer) told her son to ask the flight attendant. So the boy went down the ailse and asked the flight attendant the same question.
The flight attendant, who was very busy at the time, smiled and said,
"Did your mom tell you to ask me?"
The boy said, "Yes she did."
"Well then, you go and tell your mother that there are no baby airplanes because WestJet always pulls out on time. Have your mom explain that to you."
