started chewing, only to find that a portion of the McNugget was unchewable. He worked at it for a while and then spit it out into a napkin. He couldn't figure it out and took it up to the counter and asked what the hell was in his McNugget. And "supposedly" it ended up being a chicken's asshole. That's why it was impossible the chew because it was the rectum which is muscular and shit. I don't know if I believe the story or not, but either way, it always swayed me from eating them.
