A blonde woman finds herself sitting next to a lawyer on an airplane. The lawyer keeps bugging her to play a question and answer game, and he will even offer her ten-to-one odds. If she can’t answer one of his questions, she’ll pay him five bucks. And if he doesn’t the answer one of her questions, he’ll give her $50. She agrees.

“What’s the distance from the earth to sun?” he asks. She hands him 5 bucks.

Then she asks, “What goes up a hill with three legs and comes back down with four legs?” The lawyer thinks for a long time and finally gives up and hands the blonde $50. Then the lawyer says, “Hey, what’s the answer to your question?”

The blond says nothing and hands the lawyer five bucks.
