Yesterday was Polar Bear Day….so, the only Polar Bear joke I know. At the North Pole, a young polar bear asks his father, "Dad, am I a polar bear?" His dad replies "Well son, I am a polar bear, your mom is a polar bear. Your grandfather and your grandmother are polar bears. So yes, you are 100% polar bear. Why do you ask?" The young polar bear replies -- "Because I'm REALLY cold!"
