Q: When do you think the first airplane was made?
A: A real long time ago, before I was born.
Q: What makes it fly? A: the wind.
Q: How does the wind do that? A: It lifts the plane up.
Q: Why doesn't the wind lift you up? A: I'm too heavy.
Q: Are you heavier than the plane? A: No, but it's meant to fly, I'm not.
