I found another reason beyond the feces to not like these things. I can't stand anything with a "chant". I lip synced my way through Marine Corps boot camp. I just don't do chants. They don't motivate me; I only get pissed off at all the noise. I did not realize they did the chanting. Actually, the Tough Mudders with mouthfuls of shit makes me smile.
