A witness to an automobile accident was testifying. The lawyer asked him, "Did you actually see the accident?" The witness: "Yes, sir." The lawyer: "How far away were you when the accident happened?" The witness: "Thirty-one feet, six and one quarter inches." The lawyer (thinking he'd trap the witness): "Well, sir, will you tell the jury how you knew it was exactly that distance?" The witness: "Because when the accident happened I took out a tape and measured it. I knew some annoying lawyer would ask me that question."
