You jest - but you could actually make $$$ - just get some empty canning cans and print up some labels.
Kangaroo Farts. Can capacity: 4 dozen farts worth 100 Carbon Credits. DO YOUR SHARE! Buy now. (The bearer of these cans will then be free to pollute at will, just like Gore and his Gang.)
Gore and Gang -= 10,000 of them - flew in private jets this past week to Bali for a GW conference. (Think of the massive amount of Carbon Credits they must've bought to offset the jet fuel and all that that little holiday cost.) Guess he didn't want to risk a repeat of their conference a couple years ago in New York that was canceled due to a blizzard.
In the meantime, I wish he'd send someone up here to my house and shovel some of the global warming off my porch and dig my car out.
