Carbon credits for sale!

I noticed this exciting opportunity over at Wizbang, where commenter jhow66 offers a unique deal on carbon credits:

If anyone wants to buy "carbon credits", I sell them for $25.00 per large zip-lock bag. This way instead of farting into the open air, I will fart into the bag and close it fast. This will cut down on the amount of methane released into the air which then can be used as a "carbon credit" This way you can take the $25.00 fart bags and use them as credit to use $25.00 worth of electricity more each month. On days when I have lunch that include navy or pinto beans there will be a discount of $5.00 per bag. Order must be in by no later then the 3th of each month. Orders will be "filled" as they are dated. I am working up a deal with area farmers to use their herd animals. In this deal you will be able to purchase a cork to insert in the rectum (a** for those with limited schooling) of each animal to prevent the release of methane gas. A signed receipt will be given with cork purchased for your proof of your "carbon credit"... Yours truly, Organic Carbon Credits Inc. P O Box # OU812 Area 51, NM
