Chalkboard: I will not sell school property

Couch Gag: Homer pushes everyone else off of the couch.

This episode marks the first appearance of Dr. Nick and Lionel Hutz

Homer's Brain: A million dollars. My wife cost me a million dollars.
Marge: Homer would you like some more macaroni and cheese?
Homer's Brain: Yeah, a million dollars worth, you treacherous snake woman.
Homer: No, thank you.
Marge: Some string beans?
Homer's Brain: No, I don't want any string beans either, you two-timing, backstabbing--Uh-oh. Better answer.
Homer: No, thank you.
Marge: Some celery with cream cheese on it?
Homer's Brain: Just mouth polite nothings.
Homer: No, thank you.

Dr. Nick: Bad news. Your son is a very sick boy. Just look at the X-rays. See that dark spot there? Whiplash.
Homer: Whiplash? Oh no!
Dr. Nick: And this smudge here that looks like my fingerprint? No, that's trauma.
Bart: Am I going to die?
Homer: (Sobbing) Yes! You're going to die!
Marge: Homer!

Bart: I did go away, mom, I was miles and miles and miles away. Dying in agony in the pits of hell. And you were there! And you, and you, and you... and you I've never seen before!
Homer: (to Lionel Hutz) Yeah who are you anyway? I saw you chasing Bart's ambulance.

Judge: Mr. Burns, I must warn you that if you continue to disrupt the court in this way, I will have to cite you for contempt.
Mr. Burns: You wouldn't dare!
Judge: Well, no, um, I guess I wouldn't.

At Moe's Tavern, in the close-up of Marge when she says "Homer, look at me," the window behind her has a different pattern than in the other shots (2 rows of red tiles instead of 3).

After Marge testifies, Mr. Burns' lawyer says "Thank you very much Mrs. Simpson", and when he does the top of his head above his glasses is less paler than the rest of his face.

During Marge's testimony, Lionel Hutz has a neat stack of papers in front of him. But in the close-up when Homer and Hutz both cover their eyes, Hutz has several pieces of crumbled paper and a broken pencil in front of him.

Tale Of Two Cities

Mr. Burns: Just give him a nickel and let's get going.

This is a reference to the novel A Tale Of Two Cities. In the book, the Marquis St. Evermonde runs over a boy in the street and just tosses the father a coin.

Rolling Stones

When the Devil says, "Please allow me to introduce myself," it is a parody of the opening line in the famous Stones' song "Sympathy For The Devil".
