Carrying on from an intersting fact pointed out by Ska, what interesting facts do you know?
Well....
1. Dogs cant look up
2. Lift a dogs tail and it will wink at you
3. Printer manufacturers print invisible yellow dots on consumer's prints that check to see if a person is printing counterfeit money. the yellow dots are the serial number of the machine, this security feature is most commonly found on high end digital presses to combat counterfeiting. the dots are printed across the sheet and are hardly "invisible" and can be seen with a good eye or under a loupe.
