2 guys go on a hike in the woods, one is carrying a gun, the other a large rock, the one with the rock asks the other one ehat the gun is for, he says in case we run into a wild animal, I can shoot it and escape. He then asks the other ine what the rock is for, he says in case we run into a wild animal. The guy with the gun says a rock will not do much good against a wikd animal, the one with the rock says no but it will knock you out long enough for me to get the gun shoot the animal and run away.
