Anatomy lesson from Gavin

Gavin just explained to me how potty and poopy come out....

When you drink something, it floats in your belly and then in your penis for a while, then it "pops" out. When you eat something, you chew it, it floats in your belly like potty, then it goes to your back and then to your, bottom and comes out. Then he pondered how funny it would be if your bottom was in the front and your penis in the back. He said that poopy comes through your back because that's where your bottom is, in the back.
