Stereograms

A hunter ventures into the forest to hunt a bear, armed with his trusty 22-gauge rifle. After some time, he spots an enormous bear, takes aim, and fires. The smoke clears, but the bear has vanished.
Moments later, the bear taps the hunter on the shoulder and says, "Nobody shoots at me and gets away with it. You have two options: I can tear out your throat and eat you, or you can drop your pants, bend over, and I'll do as I please." The hunter, fearing death, drops his pants and bends over, allowing the bear to do as he said.
Once the bear has left, the hunter pulls up his pants and hobbles back into town, bow-legged and furious. He purchases a much larger gun and returns to the forest. He spots the same bear, takes aim, and fires. The smoke clears, and the bear is gone.
The bear taps the hunter on the shoulder once more and says, "You know the drill." Humiliated, the hunter pulls up his pants, drags himself back to town, and buys a bazooka. Now seething with rage, he returns to the forest, spots the bear, aims, and fires. The blast from the bazooka sends him sprawling onto his back.
As the smoke clears, the bear looms over him and says, "This isn't really about hunting for you, is it?"
