"Backwards Writing" is the 5th episode in Season 1 in Angry Kid.
Angry Kid and Lil' Sis are in the back of Dad's car. Angry Kid asks Dad why the word "Ambulance" is written backwards on the ambulances. Dad begins to explain, only for Angry Kid to start writing backwards messages to his father. Extremely annoyed, Dad starts repeatedly hitting Angry Kid with a newspaper every time he shows a new sign, with Lil' Sis encouraging Dad with signs as well.
