"Drinking Jet Fuel" joke

A couple of airplane mechanics, drinking buddies, are in a Newark hangar where the runway is fogged in and they have nothing to do.
"Geez, I sure wish we had something to drink," Jim says.
"Me too," says Bob. "You know, I hear you can drink jet fuel and get a real buzz. Let's give it a try."
So they proceed to drink jet fuel, get smashed, and have a beautiful time as only drinkin' buddies can.
The following morning, Jim expects his head to explode when he gets up, but is pleasantly surprised that he has no hangover at all. Then the phone rings and it's Bob asking Jim how he feels.
"I feel great," Jim says. "No hangover at all! How about you?"
"I feel great too," replies Bob.
"That jet fuel is great stuff and no hangover," says Jim. "We ought to do this more often."
"Yeah, well there is one thing." Bob replies. "Have you farted yet?"
"No, why?" Jim asks.
"Well, don't, because I'm in PHOENIX!!" yells Bob.
