Arm Pits and Chest Hair

Luke to Alex: Alex, I can't wait to be B's age so I can have hair in my arm pits. Does B have hair in her arm pits?
Alex: I don't know, maybe?
Luke: Well, when I'm big like dad and B I want hair in my arm pits AND on my chest. (As he pulled up his shirt and is checking out his chest)
 Alex: Me too. Lots and lots of hair in my arm pits and my chest.
