EPA administrator Lisa P. Jackson was on the Daily Show last night, where she promised she would not regulate Jon Stewart's breathing, even though he admitted that he emits carbon dioxide.
UPDATE: EVIDENTLY I DO NOT KNOW HOW TO WORK THE INTERNET. This is an old (but still awesome) interview. New and awesome interview here. (I probably should have been tipped off when he called her the "new" EPA administrator.)
