It's been a tough week for The Onion -- it was hacked by the Syrian Electronic Army -- but it really knocked this one home. Fart Scroll. Code to make your website fart.
The code is a simple enough. Just include "fartscroll.min.js" on your page, and then define how often (how many pixels of scrolling) you want the site to make a fart noise. Or, better, sneak onto your friend's Tumblr or Wordpress and slip the code into their themes without telling them. [Github via Hacker News]
