Ben's a critic

One of Ben's favorite pastimes in the car is to make Keith draw on one of those mini magnadoodle thingys.
Tonight, he commissioned a picture of "a baby sister."
I never actually saw any of the artwork, but the dialogue speaks for itself.

K: There! A baby sister.
B: No!! A BABY.
K: Oh. Okay. Let me try that again.... How about this?!
B: That's not a baby - that's a carrot.
K: Hmm. You're actually right about that.
