A Neat Party Trick

1. Tell an acquaintance that if a twenty dollar bill is folded a certain way an image of the Twin Towers on fire will appear.
2. They may have seen the trick before and think it's stupid or have never seen it before. Come up with something clever to say like, "No, seriously, it's pretty crazy. If you have a twenty I'll show you."
3. Once the bill is in your hand, run like hell!
