Or you could read the book that, uhh, had all that dialogue before the movie did. Just sayin.

OT: Fuck Mickey Mouse with a big rubber dick: George Carlin.

For most films I would say go read the book but the film is so pure to the source material and it's just so well done. I honestly think for the type of film that fight club is, it's much better than the book

Third or fourth panel, probably. Then again.

Villain stands imposing and gives monologue to bound hero.

"The device will be carefully hidden underneath the structure...then bangarang"
"Bangarang?"
"Bangarang."
"That it?"
"Yep."
"Doesn't seem like a very climactic end."
"Why?"
"That."
Secondary lead stands behind villain.
"Bangarang, ************."

Never mind, the other two are better.
