A new soldier was on sentry duty at the main gate. His orders were clear - no car was to enter unless it had a special sticker on the windshield. A big Army car came up with a general seated in the back. The sentry said, "Halt, who goes there?"
The chauffeur, a corporal, says, "General Wheeler."
"I'm sorry, I can't let you through. You've got to have a sticker on the windshield."
The general said, "Drive on!"
The sentry said, "Hold it! You really can't come through. I have orders to shoot if you try driving in without a sticker."
The general repeated, "I'm telling you, son, drive on!"
The sentry walked up to the rear window and said, "General, I'm new at this. Do I shoot you or the driver?"
