A couple of plane mechanics, drinking buddies, are in the hangar at Newark where the runway is fogged in, and they have nothing to do.
John says, "Man, have you got anything to drink?"
"Nah," says Bill, "But I hear that you can drink jet fuel and it will give you a real buzz."
So they proceed to drink jet fuel, get smashed, and have a beautiful time as only real drinkin' buddies can.
Next morning, John expects his head to explode when he gets up, but is pleasantly surprised that he has no hangover at all.
The phone rings.... with Bill asking John how he feels.
"I feel great!" says John. "No hangover!"
"Me neither," says Bill. "That jet fuel is great stuff.... and no hangover," says John. "We ought to do this more often."
"Yeah," says Bill, "But there is one thing. Did you fart yet?"
"No, why?"
"Because I'm in Phoenix."
