I can't get the actual quote right now, but I found very hilarious the line where Faile thinks the creator has a sense of irony when she was finally carrying the horn of valere She was the hunter of the horn after all!
"Philosophers claimed the Pattern did not have a sense of humor. The Pattern, and the Wheel, simply were, they did not care, they did not take sides. However, Faile could not help thinking that somewhere, the Creator was grinning at her. She had left home with her head full of arrogant dreams, a child thinking herself on a grand quest to find the Horn. Life had knocked those out from under her, leaving her to haul herself back up. She had grown up, had started paying mind to what was really important. And now . . . now the Pattern, with almost casual indifference, dropped the Horn of Valere into her lap."
"You didn't listen. I didn't come here to win, I came here to kill you"

My quote may be slightly off but this moment was awesome!
"He came like the wind, like the wind touched everything, and like the wind was gone."
The whole discussion with Mat and Rand was hilarious, but I think my favorite section
"...................I could bloody try. No offense, Rand, but you're going to go mad and all. I figured I'd give you one less friend nearby to kill. You know, save you some trouble. What did you do to your hand, by the way?"
"Demandred! You call for the Dragon Reborn! You demand to fight him! He is not here, but his brother is! Will you stand against me?"
-Galad
Even though he loses, I thought it was a pretty epic entrance
Almost anything Mat said was wonderful and hilarious.
Possibly my favorite (on the comedy side of things) line in the book came from an unexpected source, though. Elayne!
"...by a bloody goat's left stone!"
Oh man, spent quite some time laughing at that. It was great to finally see some examples of all these creative curse words she's been learning all along.
