2000 Chilean Peso bill - interesting little window on the left-hand side. It might be some sort of anti-counterfitting device, but if that was so, how come 5000 Chilean Peso bills don't have it?
I think it'd be a good idea if Euro bills circulated in Spain had a similar window that could be used to look at Spanish women. Spanish women are so hot that looking directly at them is like staring at a solar eclipse - dangerous to do, unless you want to burn out your corneas!
