Only a little boy would think this way..
I caught my son picking his nose and eating it. Disgusting! I don't know why small children are such nasty creatures.
"That's disgusting! Do you realize how disgusting that is? Eating boogers is as bad, if not worse, than eating poop. Do you know that? Boogers are the trapped germs of your body trying to get out. They're absolutely filthy. Poop, amazingly, is actually cleaner than boogers. That's how disgusting that is!"
To which he responds:
"Are you saying I should eat my poop too?"
Sigh.
