No, but I have a good bear joke, it's a classic so sorry if you've heard it before.

Say you're being chased by a bear in Alaska. Obviously you want to know which kind of bear you're being chased by. So what do you do?

Easy. Climb a tree. If it's a brown bear, it'll climb up the tree after you and eat you. If it's a grizzly, it'll just knock down the whole damn tree. Then it'll eat you.
