Homer: Good news, Lisa! I don't need your mother anymore. I've created a replacement for her that's superior to her in almost every way!
Lisa: Dad, that's just a plant.
Homer: Lisa! You will respect your new mother! Now, give her a kiss. Kiss her! (he knocks the plant out of the treehouse) Aah! Oh my god, oh my god, oh my god! All right, let's get our stories straight she tripped, right?

Marge: Homer I really don't like you telling personal secrets in your class.
Homer: Marge I didn't tell em personal stuff.
Marge: Today at the Kwik-E-Mart everyone knew I dyed my hair blue.
Homer: Oh you mean about you?

Bart: I missed you so much that I couldn't concentrate in school and I got an "F."
Homer: This is dated two weeks ago.
Bart: Oh, sorry. Here's a fresh one.

Homer: Oh. And how is education supposed to make me feel smarter? Besides, every time I learn something new, it pushes some old stuff out of my brain. Remember when I took that home wine-making course and I forgot how to drive?
Marge: That's because you were drunk!
Homer: And how.

Lisa: Will you be lecturing from a standardized text or using the more Socratic method of interactive class participation?

The whole freaking system is out of order! You want the truth? You want the truth? You can't handle the truth! 'Cause when you reach over and put your hand into a pile of goo that was your best friend's face, you'll know what to do!! Forget it Marge, it's Chinatown!!!
Marge: Homer, don't ever tell them personal stuff about me again!!
Homer (sheepishly): Yes ma'am.
