At a trial, an attorney was putting witnesses through an exacting cross-examination, and was taking great delight into getting witnesses to admit that they did not remember every single detail of accident. The attorney knew that no witness has a perfect memory and he had honed his skills in exploiting minor inconsistencies and lapses of memory in order to challenge the credibility of witnesses. After a series of scathing cross examinations, he was looking forward to his examination of yet another witness.

"Did you actually see the accident?" he asked.

The witness responded with a polite, "Yes, sir."

"How far away were you when the accident happened?"

"I was Thirty-four feet, seven and three quarters inches away from the point of collision."

"Thirty-four feet, seven and three quarter inches?" the attorney asked, sarcastically. "Do you honestly expect us to believe that your memory is so good, and your sense of distance is so precise, that months after the accident you can come into court and give that type of detail?"

The witness was unphased. "Sir, I had a hunch that some obnoxious, know it all attorney would ask me the distance, and would try to make it seem like I was lying if I could not give an exact answer. So I got a tape measure, and measured out the exact distance."
