Yesterday at lunch

I overheard a conversation between Tyler and Brody yesterday at lunch while putting in a load of laundry.  It went something like this:

Tyler: "If you don't have a mouth you can't talk, right Brody?"
Brody: "Yeah, and if you don't have eyes you can't see, right?"
Tyler: "Yeah, and if you don't have ears you can't hear anything, right Brody?"
Brody: "Yeah, and if you don't have a nose you can't wipe it when you have snot all over."
Tyler: (silence)
Brody: "And if you don't have hair.............." (nothing)
