狗要叫 and 羊要叫

Nathan has entered a stage that he like to do things he was told not to do.
Today he spread catch-up all over his face, and was punished by mommy.

But sometimes he will do something very funny. Like when we ask him to repeat the book三字經, he automatically translate "DON'T" into "DO"

so "苟不教，性乃遷" will become "狗要叫，性乃遷"; and "養不教" becomes "羊要叫"

Don't have the catch-up picture, but this one is close.
