An Icy Morning Moon

It was -4 when I got up this morning. Someone reminded me of the Polar Bear Joke recently........

Short version:
Mammy, Am I a polar bear, yes dear you are.
Mammy, Are you sure I'm a polar bear, yes of course you are dear.
Mammy, I don't think I'm a polar bear, (exasperated mammy) you are a polar bear, why do you keep asking?

Because I'm feckin' freezin'
