Where does fart gas go if its not expunged from the anus?

Farter in Fremont, Fart gas, if not released through the external anal cavity, is usually absorbed through the walls of the large intestine and released through glandular secretion around the eyes, nose, lips and mouth. That glistening sweat on your top lip...yep...fart gas. Just got home from your afternoon jog and sweaty on your brow?...yep...fart gas. Who knew?
