Who Shot the Big Buck?

Three friends decided to go hunting together. One was a lawyer, one a doctor, and the other a preacher. As they were walking, along came a big buck. The three of them shot at the same time and the buck dropped immediately. The hunting party rushed to see how big it actually was. Upon reaching the fallen deer, they found out that it was dead but had only one bullet hole. A debate followed concerning whose buck it was. When a game warden came by, he offered to help. A few moments later, he had the answer. He said with much confidence, "The pastor shot the buck!" The friends were amazed that he could determine that so quickly and with so little examination. The game warden just smiled. "It was easy to figure out. The bullet went in one ear and out the other."
