Grandpa: My Homer is not a communist. He may be a liar, a pig, an idiot, a communist, but he is not a porn star.
Grandpa: Dear Mr. President, There are too many states nowadays. Please eliminate three.
P.S. I am not a crackpot.
Marge: Grandpa, this flag only has 49 stars on it
Grandpa: I'll be deep in the cold, cold ground before I recognize Missourah!
Homer: Hey boy! Wanna play catch?
Bart: No thanks dad.
Homer: When a son doesn't want to play catch with his father something is definitely wrong.
Grandpa Simpson: I'll play catch with you!
Homer: Go home.
Lisa: I'm an ugmo.
Homer: Now, that's not true. You're cute as a bug's ear.
Lisa: Father's have to say that little stuff.
Homer: Dad, am I cute as a bug's ear?
Grandpa: No. You're homely as a mule's butt.
Homer: There. See?
Homer: There's your giraffe, little girl.
Ralph Wiggum: I'm a boy.
Homer: That's the spirit. Never give up.
Homer: Marge? Since I'm not talking to Lisa, would you please ask her to pass me the syrup?
Marge: Dear, please pass your father the syrup, Lisa.
Lisa: Bart, tell Dad I will only pass the syrup if it won't be used on any meat product.
Bart: You dunkin' your sausages in that syrup homeboy?
Homer: Marge, tell Bart I just want to drink a nice glass of syrup like I do every morning.
Marge: Tell him yourself, you're ignoring Lisa, not Bart.
Homer: Bart, thank your mother for pointing that out.
Marge: Homer, you're not not-talking to me and secondly I heard what you said.
Homer: Lisa, tell your mother to get off my case.
Bart: Uhhh, dad, Lisa's the one you're not talking to.
Homer: Bart, go to your room.
