If you know of a smell worse than sick fart gas, list it below. I can only think of a few smells that even rival "sick fart gas", but I'll start off with a few. Feel free to add to this list. I'll approve the submissions as time allows. :) http://www.squidoo.com/worst-smell-everworst-smell-ever Fri, 17 Feb 2012 15:54:16 -0600 FeedCreator 1.7.2 I still say that sick fart gas is the worst smell ever.
