I've got a bear behind

Bill's all excited about his new rifle. So, he goes bear hunting in Alaska. The first bear he sees is a little brown bear, and he kills it with his first shot. There is a tap on his shoulder, and he turns around to see a big black bear.
The black bear says, "You've got two choices. One, I maul you to death or two, we have sex."
He bends over for the bear. He's sore for 2 days, but he recovers and vows revenge.
Bill heads out on another trip to Alaska and he finds the black bear and kills him. At that moment there is a tap on his shoulder. A huge grizzly is standing right behind him.
The grizzly says, "That was a big mistake. You've got 2 choices, "Either I maul you to death or we have sex."
Bill bends over. He survives, but he's really hurting and takes quite a bit of time to recover, and, he's outraged!
Sure enough, he heads back to Alaska and finds the grizzly and shoots him at point blank range. There's a tap on his shoulder. He turns around to find an enormous polar bear.
The polar bear says, "You don't really come here for the hunting, do you?"
