"Can you turn my dollar bill into a hundred?"
How many times have you heard THAT line? - Here's the trick that shuts them up.
Take the dollar from their hands and fold it into a small packet. A snap of your fingers and you unfold what they think is a hundred bucks.
Their dollar bill is turned inside out.
- NOT UPSIDE-DOWN
- NOT A PHOTOCPOY
- REAL US CURRENCY - Totally misaligned
"Don't worry, it's still four quarters!"
Fold the freaked out bill back up and it changes back into their dollar - Give it back or, since their brains are flatlining - Put their money in your pocket...You earned it.
