A private just out of training is assigned to guard the main gate.

He is ordered to allow no one through unless they have the password.

A vehicle with a 3-star general inside rolls up. The private stops the vehicle and asks the driver for the password.

The driver doesn't know the password. The private, after saluting the general, asks him the for the password. The general doesn't know it either.

The private says, “I can’t let you through without the password.”

The general replies, “Son I'm the commander of this base and a 3-star general!”

The private says, “Sir, I still can’t let you pass."

The general tells the driver to drive on through.

The private then says to the general, “Sir I'm real new to this. Do I shoot you or the driver?”
