		Code:
	
	  // Fart every 400 pixels scrolled in the document
    $(document).fartscroll();
    // Fart every 800 pixels scrolled in the document
    $(document).fartscroll(800);
    // Fart every 100 pixels scrolled in the body (probably a bit much)
    $("body").fartscroll(100);
    // Now I'm just adding more examples to make the page longer
    $("body").fartscroll(50);
    // SO MANY FARTS
    $("body").fartscroll(5);
    // I should register fart.io for this
    $("div").fartscroll(500);
    // I should register fart.io for this
    $("body").fartscroll(400);
    // Dammit, fart.io is taken
    $(window).fartscroll(600);
    // Alright, that's probably enough examples
    $("body").fartscroll(400);
