That DVD is an insult to farting and fartists everywhere. Pump em full of White Castles and let the real methane come forth.

Edit: The front cover pic just loaded upon my log in. Coffee table farts?!!! I take back what I said. I may have to check this out to learn some new techniques. Back in high school we used to go to great lengths to produce different sounding farts. For example, bouncing one off of a USPS mailbox and opening the lid for amplification worked a lot better than we theorized.
