9+11 = 20: Unbelievable Images on the $20 Bill
- RF Cafe Cool Pic -

minimum height spacer

You're not going to believe this pair of images on the new $20 bill. A further freak coincidence is that the Islamic terrorist attack on the United States occurred on 9/11, and those numbers sum to 20 - the denomination of the bill that contains images of the twin World Trade Center towers and the Pentagon building on fire! This trick was demonstrated to me by a 17 year-old boy at my son's karate class. I made the 9+11 connection myself. Take a look!
