Bob and Pete were a couple of drinking mates who worked as aircraft mechanics in Melbourne. One day the airport was fogged in and they were stuck in the hangar with nothing to do. Bob said, "Mate, I wish we had something to drink!" Pete says, "Me too. Y'know, I've heard you can drink jet fuel and get a buzz. You want to try it?" So they pour themselves a couple of glasses of high octane hooch and got completely smashed. The next morning Bob 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 Pete, who says, "Hey, how do you feel this morning?" Bob says, "I feel great, how about you?" Pete says, "I feel great, too. You don't have a hangover?" Bob 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 Perth."
