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