These two friends decide to go rabbit hunting with bow and arrows. They convince their friend, the statistician, to come along since he doesn't get out very much. The three wait patiently out in the woods for a rabbit to pass by. Suddenly a rabbit bolts across a clearing some distance away and races toward a dense patch of trees. The first hunter whips out his bow, strings an arrow, and lets fly. "Darn," he cries, "the arrow was a foot short." Just then the rabbit bolts across the clearing from the other side of the woods. The second hunter whips out his bow, strings an arrow, and lets fly. "Darn" complains the second hunter," the arrow went a a foot long." The rabbit once more emerges from the woods and races across the clearing. the statistician starts to raise his bow and then lowers it with a contemplative expression. He takes out the stub of a pencil, finds a crumpled envelope in a pants pocket, and quickly executes some calculations on the back of the envelope. Then he looks up, smiling, as the rabbit disappears for the final time and waves the envelope in the direction of the other two hunters. "Look at this -- if you take the mean distance that the arrows went, we got the rabbit!"
