Aja baja, cookie tasty

Jan Rippe guesses that "Aja baja kaka smaka" (Aja baja, cookie tasty) was one of the things David Sundin had said to him at the start of the Surprise memory test task. “Aja baja” is a light Swedish scolding term used to, for example, remind toddlers not to touch something. The second part of what he said – “kaka smaka” – also rhymes in Swedish.
