I don't get this one, but here it goes:

Two airline pilots decide that they want to get drunk after a long flight. However, they are stranded in a dry county and don't know what to do for alcohol. Finally, one of them suggests they try drinking jet fuel. The other agrees so they try it out and get pretty wasted. The next morning pilot #1 calls pilot #2 and asks him how he feels. Pilot #2 says, "Fine, how about you?" Pilot #1 says, "Great, no hangover, nothing....but whatever you do, don't fart." "Why not," asks pilot #2? Pilot #1 replies, "Because I'm in Phoenix."
