The buck man
Another idea: Take a brown clothespin and decorate it like a rifle. Then you take some paper or carton and cut out a man who looks like a hunter, holding the rifle in his hands. After that you can try to fold the bills you want to present like bucks (hares) or just pen the bills into the clothespin. Now you can attach a little string with paper saying shot you some bucks or another nice sentence fitting the occasion.
