Two boys are having a competition. They have made a bet to see who could fart the hardest. To settle the bet, they have a pan filled with flour and leveled. Whoever can displace the most flour wins. The first boy crouches over the pan and lets one rip. When the flour settles, they see the pan has only half the flour as it did to begin with. ""I can do better than that."" Said the second boy. They refill the pan and level the top. The second boy crouches over the pan and lets a mighty one go. Only 1/4 of the flour remains. The neighbor girl who has been watching curiously walks over and asks what the boys are doing. They explain their friendly game and to their surprise, she says ""That's nothing. I can do better than either of you two."" Well, the two boys fill the pan with flour and level it. Certainly this girl has nothing to bring to the table. She crouches over the pan and lets one rip. When the flour settles, there isn't a single bit left in the pan. The boys are taken aback! The first one asks ""how in the world were you able to beat us at our own game?!"" The second boy lifts up the girls skirt to take a peek and yells ""Just what I thought! Double barrels!!""
