Bear cub comes romping up to his mother and says, "Mommy, what kind of bear am I?"

"Why, you're a polar bear, honey," sez his mother.

The cub wanders off, looking thoughtful.

After a bit, comes back and asks, "Mommy, what kind of bear did you say I was?"

Again, she say's "Well, you're a polar bear."

Again, the cub shambles off, looking thoughtful.

Then he comes back and asks once more, "What kind of bear did you say I am, Mommy?"

"You're a polar bear, honey. Why do you keep asking?"

"B-b-b-because I'm f-f-f-freezing my b-butt off!!"
