'New on Sentry Duty'

A new recruit 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 Navy car came up with an Admiral seated in the back. The sentry said,

"Halt, who goes there?" 

The chauffeur, a Third Class Petty Officer says,

"Admiral Wheeler." 

"I'm sorry, I can't let you through. You've got to have a sticker on the windshield." 

The Admiral 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 Admiral repeated,

"I'm telling you, son, drive on!" 

The sentry walked up to the rear window and said,

"Admiral, I'm new at this. Do I shoot you or the driver?"
