Balloon boobs

Rachel (23 months) has a favorite game called "What's this?" The other day she was sitting with me on my bed. (Now the rest of the story is much funnier if you understand that I have very large breasts.) She pointed to one of my breasts and says, "What's this?"
Being in a very silly mood, I replied, "Boob." She thought for a second, pointed to the other breast and repeats, "What's this?"
"Boob," I replied.
Rachel thinks for a minute, smacks both of my breasts and exclaims, "Balloons!"
