Pen Thru Dollar Bill
Imagine yourself borrowing a twenty from a friend. Reluctantly she hands over the bill. Just as she’s about to ask why you need it, you confidently shove a pen right through her money! She watches in amazement (her eyes only inches from the bill) as you pull the pen out leaving the twenty completely unharmed. She snatches the twenty out of your hand and can’t find anything wrong with it. Now she wants to see the pen. No problem, you hand it to her.
