Bertie has shockingly dirty habits, from nose picking to weeing on the flowerbed! Whenever he does anything dirty, Bertie’s family shouts, “No, Bertie! That’s dirty Bertie!” He eventually manages to kick most of his anti-social habits when they result in some unfortunate outcomes, but the nose-picking continues.
