A couple of drinkin' buddies, who are airplane mechanics, are fogged in and have nothing to do. One of them says to the other, "Man, have you got anything to drink?"
The other one says, "Nah, but I hear you can drink jet fuel, and that it will kinda give you a buzz."
So they drink it, get smashed and have a great time; like only drinkin' buddies can do.
The following morning, one of them gets up and is surprised he feels good, in fact, he feels great - NO hangover! The phone rings, it's his buddy.
The buddy says, "Hey, how do you feel?"
He said, "I feel great!"
and the buddy says, "I feel great too! You don't have a hangover?"
and he says, "No -that jet fuel is great stuff - no hangover - we ought to do this more often."
"Yeah, we could, but there's just one thing....."
"What's that?"
"Did you fart yet?"
"No"
"Well, DON'T, 'cause I'm in Phoenix!"
