"The Main Gate" joke

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. My orders are that 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 the driver?'
