Hmm, it's certainly an idea.
http://www.fartneutral.com/index.htmlFart Neutral’s goal is to bring attention to global warming in a unique and humorous way.
We offer a line of gift cards, t-shirts and other items, each of which comes with a certificate for a 1000 lbs. reduction in greenhouse gases. The 1000 lbs. greenhouse gases reduction not only neutralizes a person’s farts for one year, but it also offsets greenhouse gases created in the actual production of the apparel and gift cards. ** A purchase from Fart Neutral is truly “green from top to bottom.”
Our products make a great gift for that special someone who is notorious for greenhouse gas “production.” Wearing our apparel is a great way to start a conversation about global warming; every article of clothing comes with a free Fart Neutral™ card that fully explains the issues facing the planet. The card is also a fun way to get the attention of that cute girl at the bar (we are not responsible for any slaps, tossed drinks or children that result from its use).
If the word fart offends you, we offer other products that get the point across, but without using the "f" word. See our Products page for more information on the Emissions Neutral Card.
