Scene: Gracie is in the tub, having fun with her toys when she accidentally spots Sean's belly button. Why it was exposed, I have no idea. It just was.
Gracie: Be Bo (points to Sean's belly button)
Sean: Yep, that's my be bo
Gracie: Garbage (points to Sean's belly button)
Sean: (looks down) Yeah, I guess your right. (pulls out a piece of flint)
