"Anyone who isn't dead or from another plane of existence would do well to cover their ears right about . . . now."
"Tell someone you're the Metatron and they stare at you blankly. Mention something out of a Charleton Heston movie and suddenly everyone's a theology scholar."
"Oh, Bartleby, was Wisconsin really that bad?"
"Give over, I couldn't rape you even if I wanted to. Angels are ill-equipped - see? I'm as anatomically impaired as a Ken doll."
"I say we get drunk, cause I'm all out of ideas."
"I'm pissed off, is what I am! Do you go around drenching everybody that comes into your room with flame-retardant chemicals? No wonder you're single"
Thus starts Metatron's running gag of getting gunk all over his suit.
Metatron: (after God explodes Bartleby's head) You missed a bit...(brushes off suit)
"Metatron acts as the voice of God. Any documented occasion when some yahoo claims God has spoken to them, they're speaking to me. Or they're talking to themselves."
"We went through five Adams before we figured that one out."
[Bethany is holding a baseball bat] "Or you'll do what, exactly? Hit me with that ffffffffiiiish? [Cut to Bethany holding a fish like the baseball bat]
Metatron: I am a Seraphim.
[Bethany looks confused]
Metatron: The highest choir of angels?!
[Bethany still doesn't get it]
Metatron: You DO know what an angel is, don't you?
[Bethany slowly nods]
Bethany asking Silent Bob why he carries an odor-killing spray bottle. He points to Jay, who has just farted.
Most of Bartleby and Loki, but a particularly good one is:
Loki: Let it never be said that your anal-retentive attention to detail never yielded positive results.
Bartleby: You can't be anal-retentive if you don't have an anus.
Jay's massive rant at the climax is side-splitting from start to end, but peaks with his angry shout of "WHAT THE FUCK HAPPENED TO THAT GUY'S HEAD!?!" Witness it here
Loki's Establishing Character Moment in the opening when he tells a nun how Alice in Wonderland is responsible for his lack of faith in religion due to him seeing the story of the Walrus and the Carpenter as a commentary on the subject, the two representing the deities of the earth who fool the oysters into following them before they shuck and eat them. Funny because as ridiculous as it is, his explanation sorta makes sense.
Especially the conversation that Bartleby and Loki have afterwards (paraphrased):
Bartleby: "You have been in God's presence. He has spoken to you personally. How can you say that you don't believe in Him?"
