On a flight, a blonde sat next to a lawyer.

It was a long trip, so she quietly turned toward the window, ignoring him.

The lawyer leaned over and said:
“Let’s play a game. I’ll ask you a question. If you don’t know the answer, you give me five bucks. Then you get to ask me a question. If I don’t know the answer, I’ll give you five hundred.”

The blonde shrugged. “Okay.”

The lawyer started:
“What’s the distance between the Earth and the Moon?”

Without saying a word, she reached into her purse, handed him $5, and looked back out the window.

Then it was her turn. She asked:
“What goes up a hill with three legs and comes down with four?”

Hours passed. The lawyer racked his brain, flipped through notes, even searched his laptop. Nothing. Finally, frustrated, he handed her $500.

Then he asked:
“Okay, so what’s the answer??”

The blonde silently pulled out another $5, handed it to him, and turned back to the window.
