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.  Shane 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, DONT - 'cause I'm ringing from New  Zealand  '
