Two airplane mechanics Bob and Tim work at Atlanta airport. Atlanta gets fogged in one night and nothing can take off or land so Bob and Tim have nothing to do. After work Bob and Tim usually have a drink on their way home, so Bob says to Tim, “I heard that you can get a buzz off drinking jet fuel.” Since they have nothing better to do, they try it. Finally, their shift is over and they get to go home. Next morning Bob calls Tim and says, “How are you feeling?” Tim says he's fine, never felt better. Bob asks, “Do you have a hangover?” Tim says no. Then Tim says, “Wow this is great! We can drink all we want and not get a hangover.” Then Bob says, “Well, there is one side effect, Tim. Have you farted yet?” Tim says, “No, why?” Bob says, “I'm calling you from Detroit!”
