Quack-up.

I'll give you a rubber duck is probably usually appropriate for the Scottish weather. But have you ever seen a duck with thistles strategically placed like this? And more importantly, doesn't it chafe?

Or maybe the question should be, since when do ducks have nipples?

Maybe they thought it was a platypus.

I love the fact that when first discovered, the platypus was thought to be an elaborate hoax. A venomous mammal with a bill that lays eggs - it's like an evolutionary Mr Potato-Head.
