Will you ever learn?

I don't want to be a negative blogger, (there's another guy that does that) but I have a friend who never learns from his mistakes. I'm sure we all have one. I told him this joke and he didn't get it. Too bad common sense isn't something you can get a college degree in. I know a few people that could use a bachelors degree in it. Here's the joke:

• A hunter goes into the woods hunting for a bear. When he is deep in the woods he feels a tap on his shoulder. He turns to see an enormous grizzly towering above him. Before he can fire, the beast rips the rifle out of his hands and proceeds to sodomize him. Mortified, the hunter retreats to his cabin, arms himself with a double-barreled shotgun, and races back into the woods to find and kill his furry assailant. But once again, the bear sneaks up behind the hunter, pulls the weapon from his hands and has his lusty way with him. Undeterred, the hunter equips himself with a machine gun and treks back into the woods where he is again ambushed, disarmed and raped by the bear. Now, apoplectic with moral outrage, the hunter flies to a third world country where he buys a heat-seeking, shoulder-launched, nuclear-tipped rocket from an international arms dealer. Convinced he finally has the upper hand, he returns to the woods, tracks the bear to his lair and patiently waits to vaporize him. And yes, again, the bear surprises, disarms and sexually assaults him. But this time, before the hunter can run off to acquire more lethal armaments, the bear enfolds him in his massive arms and says, "You don't really come out here to hunt, do ya?"
• My friend thought the moral was "beware of homosexual bears."
