A private is alone on sentry duty when the phone rings in his box.
Hello?' a voice shouts down the phone.
'Are there many vehicles in the officer's car park?' The sentry steps out of his box and looks across the road, where a solitary Bentley is parked.
He goes back to the box and answers the caller.
'Only that fat bastard General Jackson's car,' he says.
'Do you know who you're talking to?' booms the voice down the line.
'This is General Jackson!' 'Do you know who you're talking to?' the private replies, completely unflustered.
'No,' General Jackson answers.
'Well, fuck off then, fat arse,' the private replies.
