How Pretty Am I?

Me, to Sarah, after drying her hair: Oh Sarah, you look gorgeous. You are the prettiest girl ever!
Sarah: I am?
Me: Absolutely!
Sarah: Prettier than Carrie Underwood?
Me: Oh yes!
Sarah: Prettier than a queen?
Me: Definitely!
Sarah: Prettier than Mary?
Me: Mary? You mean the Mother of God?
Sarah: Yes.
Me: Mmmmh. Well that's a tricky one.
Sarah, giggling: Yeah. That is a tricky one!
