A baby polar bear is sitting on an iceberg with his mum. The baby asks his mum, 'Mum, are you sure I'm a polar bear?' His mum says, 'Yes, darling, of course you are.' A few minutes later he asks a second question, 'Mum, are you sure I'm not a brown bear?' 'No dear, you're not a brown bear.' 'Well what about a black bear? Maybe I'm a black bear.' 'No dear, you're not a black bear. Look at your fur – it's white.' 'Well if I'm not a brown bear or a black bear, maybe I'm a grizzly bear.' 'No dear, you're not a grizzly bear. You're a polar bear, like your mum and dad.' 'Why do you keep on asking these stupid questions?' his mum asks. 'Well mum', says the baby, 'I'm asking these questions because ... I'm freezing.' https://339efcb25eb75e967b0d-ff8eeadd950d51fd1fc939dca75b3973.ssl.cf1.rackcdn.com/assets_green.swf
