Fart apps are one of those things that are just immune to redundancy. The latest fart app that I've discovered for the PlayBook via BlackBerry App World, is one called "Mega Fart" by developers, Toysoft Development Inc. With Mega Fart you get 10 different funny, and quality, fart sounds. It's compatible for the PlayBook, and cost just $0.99. A small price to pay to get a few laughs out of your friends and family. What are you waiting for? Let er' rip!
