Polar bears are black

Its true, polar bears are black. Their black skin helps them absorb heat from the sun. You're thinking well their fur is white. Wrong. Its transparent. The hollow fibres reflect light so as to appear white.

The most visible part of a polar bear is his nose. A polar bear's nose is visible for many kilometres against a snowy background, so when hunting they cover their nose with a paw.

Well Andy, if you'd watched QI you'd have discovered that the 'covering their nose with their paw' is not true.
