If you ever testify in court, you might wish you could have been as sharp as this policeman.

He was being cross-examined by a defense attorney during a felony trial. The lawyer was trying to undermine the policeman's credibility....

Q: "Officer -- did you see my client fleeing the scene?"

A: "No sir. But I subsequently observed a person matching the description of the offender, running several blocks away."

Q: "Officer -- who provided this description?"

A: "The officer who responded to the scene."

Q: "A fellow officer provided the description of this so-called offender. Do you trust your fellow officers?"

A: "Yes, sir. With my life."

Q: "With your life? Let me ask you this then officer. Do you have a room where you change your clothes in preparation for your daily duties?"

A: "Yes sir, we do!"

Q: "And do you have a locker in the room?"

A: "Yes sir, I do."

Q: "And do you have a lock on your locker?"

A: "Yes sir."

Q: "Now why is it, officer, if you trust your fellow officers with your life, you find it necessary to lock your locker in a room you share with these same officers?"

A: "You see, sir -- we share the building with the court complex, and sometimes lawyers have been known to walk through that room."

The courtroom erupted in laughter, and a prompt recess was called.

The officer on the stand has been nominated for this year's "Best Comeback" line -- and we think he'll win.
