A baby polar bear is sitting on an iceberg with his mother. Suddenly he asks, "Mom, am I really a polar bear?" His mother replies, "Why, of course, dear." A minute later, he asks again, "Mom, am I really a polar bear?" His mother says, "I'm a polar bear, your daddy is a polar bear, you are a polar bear. Now finish eating your seal!" A minute later, the baby asks the question again. Annoyed, the mother shouts, "Yes! Why do you keep asking?" To which the baby shrieks, "Because I'm freezing my *** off."
