Okay Marge, its your child against my child. The winner will be showered with praise. The loser will be taunted and booed until my throat is sore.— Homer
One of the staples of the Simpsons' opening credits is the blackboard gag. Bart writes something on the chalkboard as a punishment, quite often ironic. Here we list them all, including screenshots where useful. Any episodes not listed here do not have blackboard gags.
Season 12 starts 27th September.
