Why is she naked?

We were over at Luke's house today (our usual Sunday routine). The boys are playing pool and Kaitlyn and Aaliyah are sitting at the table playing with their Barbies. Kaitlyn says to Aaliyah "why is she naked?". No lie, all 4 guys stopped their pool game and turned around, at the same time. I looked at them and started laughing. I said she was referring to the Barbie, you can keep on playing pool.
