Dave and Jim were a couple of drinking buddies 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. 
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 вооzе 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 Perth!"
