"Oof."

"Boof.... Now you say 'Boof'."

"Boof."

"OK - go again momma."

"Boof."

"No! That's not right... Say 'Oof'!"

"How do I know which one to say?"

"Just say 'Boof'."

"Moof."

"No, 'Boof'!"

"What if I don't want to say Boof? What if I want to say Koof?"

"You don't. You say 'Boof'."

"Doof.... Troof... Proof?"

*heavy sigh* "Momma, you don't know how to play this game very well, do you?"
