Bud and Jim were a couple of drinking buddies who worked as airplane
  mechanics in Atlanta. One day the airport was fogged in and they were
  stuck in the hangar with nothing to do.
  Bud 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 hooch
  and get completely smashed.
 
  The next morning Bud 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?"
   Bud says, "I feel great. How about you?"
   Jim says, "I feel great, too. You don't have a hangover?"
   Bud 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 PHOENIX!!!"
