“What’s the weight of the moon?”
The blonde says “I don’t know” and give him $5
Then she asked him: “what goes up with 2 legs but comes down with 3”
The lawyer doesn’t know the answer to the question, he doesn’t wanna admit it. So he spends the rest of the flight trying to figure it out.
During this time the blonde naps in peace.
When the plane lands the lawyer hands the blonde $300.
As they’re getting off the plane the lawyer runs up to her and says :
“Please!.. What’s the answer to the question?”

The blonde smiles and hands him $5 and calmly walk away.
The lawyer knew he was just scammed.
