Perry White: Oh, I suppose you expect me to pry into your life to try and find out what's bothering you and then relate it to some obscure event in the life of Elvis Presley. Well I—I'm just not gonna do that.
Lois Lane: Why not?
Perry: Well, for one thing, any connection I made would probably be vague and not particularly useful. And for another, if I did that, it would seem like I cared more about telling my story than helping you with your problem.

Ellis: My buddy Keith went camping out on top a building once. He was shooting crows but the police were too busy tear gassing him to ask what he was doing up there. He screamed for an entire year every time he opened his eyes. Oh man... at first it was funny... then it got sad... but then it got funny again.

"'Ooh, this routine's gone on a bit long. I expect he'll stop doing it and talk about something else.' No, I won't do that."

Have you ever tried the experiment of saying some plain word,
such as "dog," thirty times? By the thirtieth time it has
become a word like "snark" or "pobble." It does not become tame,
it becomes wild, by repetition. In the end a dog walks about
as startling and undecipherable as Leviathan or Croquemitaine.
It may be that this explains the repetitions in Nature, it may be
for this reason that there are so many million leaves and pebbles.
Perhaps they are not repeated so that they may grow familiar.
Perhaps they are repeated only in the hope that they may at last
grow unfamiliar. Perhaps a man is not startled at the first cat he sees,
but jumps into the air with surprise at the seventy-ninth cat.
—G. K. Chesteron, Alarms and Discursions

The joke was probably funny about a minute ago, but you just keep going! You go on for so long that it goes all the way around the spectrum of comedy, until it is funny again!"

"Damn it, this scene is taking freaking forever."

"It's just like [the humor of] South Park, people said that it's like—so long where it's like—it's funny, and then it's not funny, and then it's funny again."
