The best part of that scene is this:
St. Lucian: Tell us, good Reverend, what great deeds have
you done to inspire the hearts of men?
Lovejoy: Well, I had the vestibule recarpeted.
St. Donickus: ...I've appeared in over eight thousand visions, and that's the
lamest reply I've ever heard.
Lovejoy: Oh, now please, I, I thought saints were supposed to be friendly.
St. Donickus: You... you're just lucky
God isn't here.
^ Funny how a supposed saint doesn't know God is omniscient.
Other favorite quotes:
Summer of 4'2'':
Marge: So, did you call any of your friends?
Lisa: Friend? These are my only friends. Grownup nerds like Gore Vidal, and even he's kissed more boys than I ever will.
Marge:
Girls, Lisa. Boys kiss
girls.
Also:
Homer: "Wel-diddly-elcome, Simpsons." Oh, jeez, he actually wrote "diddly"!
Lisa the Skeptic:
Bart: Dad, why aren't you saying anything? Where's our motorboat?
Homer: I didn't like it. The mast had termites.
Lisa: Why would a motor boat have a mast?
Homer: Because! The thingy was... shut up!
Das Bus:
Homer: Flancrest Enterprises?
Ned: Oops! That's for me! Flancrest Enterprises is my home business.
Homer: You liar! You don't have a home business, why would you make up a lie like that?
Ned: (laughs) Oh, it's true! Maude and I sell religious book rugs over the Internet!
Homer: Internet, eh?
Ned: Yes, indeedy! Making some good scratch, too!
Homer: Scratch, eh?
Ned: Yep!
Homer: Maude, eh?
Lisa Gets an "A":
Chalmers: Good lord, what a dump. It's not surprising this school was once classified
the most dilapidated in all of Missouri. (beat) That's why it was shut down and moved here, brick by brick.
Hurricane Neddy:
Ned's mother: You gotta help us, Doc. We've tried nothin', and we're all out of ideas.
Lisa on Ice:
Bart: Come watch TV with me, Dad. We missed the first two episodes of "Cops", but if we hurry we can catch the last three.
Homer: Aw sorry, Bart. Lisa and I are going out for a gelato. We'd ask you to come, but...
you know.
^ No, I don't know. Please elaborate, Homer.

The overabundance of COPS on Fox is pretty funny, too.
Bart Gets an Elephant:
Chief Wiggum: Yeah, right, lady: an elephant ran through your front yard. OK. (switches lines) Wiggum... (listens) Yeah, right, mister, mm-hmm. An
elephant just knocked over your mailbox. OK. (switches lines) Wiggum... (listens) Yeah, right, buddy, liquor store robbery, officer down. Sure. And I'm Edward G. Robinson. (hangs up) Waaaaah.
Lisa the Iconoclast:
Skinner: He's embiggened that role with his cromulent performance!
