Aussie Aircraft engineers

Shane and Phil were a couple of drinking buddies who worked as aircraft engineers in Melbourne, Australia. One day the airport was fogged in and they were stuck in the hangar with nothing to do. Phil said, 'Man, I wish we had something to drink!' Shane says, 'Me too. Y'know, I've heard you can drink jet fuel and get a buzz. You wanna try it?' So they pour themselves a couple of glasses of high octane booze and get completely smashed. The next morning Phil wakes up and is surprised at how good he feels. In fact he feels GREAT! NO hangover! NO bad side effects. Nothing! Then the phone rings. It's Shane who says, 'Hey, how do you feel this morning?' Phil says, 'I feel great, how about you?' Shane says, 'I feel great, too. You don't have a hangover?' Phil says, 'No that jet fuel is great stuff - no hangover, nothing. We ought to do this more often..' 'Yeah, well there's just one thing.' What's that?' 'Have you FARTED yet?' 'No.' 'Well, DON’T - 'cause I'm in New Zealand'
