There was once a guy named Fred who scooted in his chair during math class and it sounded like he farted. His friend, Howie, was sitting next to him and called him out on it. Fred insisted that he hadn't farted and tried to explain the situation to Howie, but Howie wouldn't believe him. Fred asked Howie how he could prove to him that he didn't actually fart. Howie said the only way he would believe that was if he had a time machine and stuck his nose by Fred's ass so he could smell if he actually farted or not. Thus, Fred dedicated the rest of his life to inventing a time machine that was capable of taking himself and Howie back to that time in math class. Fred slaved away for years, going through failure after failure, too busy to ever get a family or a real job. He became consumed by the idea of building a time machine and became a recluse, rarely leaving his house. One day it all paid off. Fred had succeeded in creating a time machine when he was 54 years old. He knew that he had to get in touch with Howie, but it had been so long since he had talked to anyone that he didn't know how. He flipped through his old phone book until he found Howie's parents number and eventually was able to track down Howie himself. Howie was surprised to hear from Fred. He had heard rumors of how Fred had gone insane and was living in some run-down house on the edge of town. Howie was curious to see how his old friend was doing, so he agreed to go out to Fred's house. When he got there, Fred immediately began rambling on about his time machine and how he could finally prove that Howie was wrong about that one time he farted in math class. Howie was pretty confused, but he decided to listen to Fred and give his contraption a try. Fred and Howie both put on the time traveling helmets and Fred pressed a button. To Howie's astonishment, they were immediately poofed back into their highschool math class, and they both looked like they were still 17 years old. Right at the time when Fred had scooted in his chair so many years ago, he pulled down his pants and let Howie stick his nose right near his asshole. Fred was so nervous from the pressure of the situation that he sharted all over Howie's face.
