No Balks

I was brushing Sarah's hair this morning, and she was stretching and wiggling her hands. Charlie was sitting near us.

C: Sarah, why are you making those weird hand signals?
Me: Maybe she wants you to throw a curve ball.
C: I can't throw a curve ball.
Me: Why not?
C: Because I don't know how. Maybe she wants me to throw a balk pitch.
Me: That doesn't make any sense. Why would she want you to balk?
C: No, not to balk. To throw my balk pitch. You know, I go like this (makes chicken arms) "Bok bok," to distract the batter, and then while he's laughing I throw my fast ball and I strike him out!
