Mouth of Money

Wanna see something really cool?
Put a five dollar bill in Fred’s mouth, and he can spit out a hundred nickels.
No. Really. Try it.
The guy’s got himself a magical mouth or something.
Same goes for a dollar bill. He’ll spit out a hundred pennies.
What about a ten-spot? Sure, give it a try. He’ll spit out a hundred dimes.
If you need a hundred Susan B. Anthonies, put in a C-note.
Out come the shiny silver little dollars. Not that you can use them anywhere.
Don’t try it with a twenty, though. Don’t try it with a twenty.
