I don't know why the topic of poop always comes up, but it does. And I don't know why I find it so entertaining. Here's another conversation with Hayes on the fascinating subject. You just might learn something.
"Food goes into your chest and then goes into the poop center."
"How does it get there?"
"It uses a slide."
"What does it do once it's in there?"
"There's a factory in there and my body paints it green, red and brown before it comes out."
