Dave  and Jim were a couple of drinking buddies who

worked  as  aircraft  mechanics  in Melbourne, Australia.
One day the airport was fogged in and they were stuck in 

the  hangar  with nothing to do.

Dave said, 'Man, I wish we had  something to drink!' 
Jim  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 Dave 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 Jim.  Jim says,
'Hey, how do you feel  this  morning?'

Dave says, 'I feel great, how about you?'

Jim  says, 'I feel great, too. You don't have a  hangover?' 

Dave  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  '
