Bud and Jim are a couple of drinking buddies who work as airplane mechanics in Miami.

One day the airport is fogged in and they're stuck in the hanger with nothing to do.

Bud says, "Man, I wish we had something to drink."

Jim says, "Me, too. Y'know, I 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: Hey, how do you feel this morning?

Bud: Great!

Jim: I feel great, too. You don't have a hangover?

Bud: No, that jet fuel is great stuff, no hangovers, nothing. We oughta do this more often.

Jim: Yeah, well, there's just one thing....

Bud: What's that?

Jim: Have you farted yet?

Bud: No.

Jim: Well, don't, 'cause I'm in San Francisco.
