A mother and her son were flying Air Canada from Toronto to Vancouver. The son (who had been looking out the window) turned to his mother and asked, “If dogs have baby dogs and cats have baby cats, why don’t planes have baby planes?”

The mother (who couldn’t think of an answer) told her son to ask the flight attendant. So the boy asked the flight attendant, “If dogs have baby dogs and cats have baby cats, why don’t planes have baby planes?

The flight attendant responded, “Did your mother tell you to ask me?”

The boy admitted that this was the case.

“Well, then, tell your mother that there are no baby planes because Air Canada always pulls out on time. Your mother can explain it to you.
