(Let's set the scene.)
Daddy is just about to get in the shower and YG needs to give him a hug and kiss goodnight. Unbeknownst to me and YG daddy was already naked and ready for the shower. And he was bending over as we walked in. YG strains her neck.
YG: Daddy, what are those?
Daddy: Daddy's balls.
YG: I want balls!! Can I have balls?!
