What would you do if you saw $100 lying on the ground?

(I got tagged by Adrienne Kress... But, the buck stops here. Tag yourself. I'm only answering one question: What would you do if you saw $100 lying on the ground?)

The money wasn't mine. Of course it wasn't. I picked it up, because it was a large amount of money. A bicycle had driven down the center of Benjamin's face. bits of dirt and mud stuck to the bottom of the bill. I could barely make out the back. I rolled the money up into a tight ball. I shoved it against my ear.

I listened to the hundred dollar bill like a conch shell. It sounded like cars driving, and elevators climbing up - up - up...
