Seriously?

Just inside Barnes & Noble.

Moon, giggling: Mom, look.
Me: What?
Moon, still giggling and nodding toward a stack of books: Look.
Me, looking in same direction: What?

Moon nods his head toward a book.
Me: What?

Moon covers his mouth and his shoulders start to shake with laughter.
Me: What?

I take a harder look at the stack of books, trying to figure out what's so damn funny.
Me: Oh, seriously?

Moon is laughing even harder.
Me: Seriously? It's that funny? "Dick" Francis?
