The entire sequence from MGS3 when you call the black guy (can't remember his name, the weapons dude) and you naked and when you call him when your inside a box. something along the lines of...
S(snake) BG(black guy)

BG-"...Snake...why are you naked?"
S-"I don't know...feels good"
BG-"But Snake, not only does it raise your visibility, it also lowers your stamina and makes it easier fro you to get sick"
S-"yea well, it feels nice like this"
BG-" yea well, you shouldn't do it. going without a shirt isn't smart."
S-"hey, i got a question"
BG-"yea Snake?"
S-"...is their any way for me to take my pants off?"
BG-" ahhhh Hell no. got me working with the crazy guy."
S-"hahaha"

o yea, and when you eat a Russian Glow cap mushroom and you call paramedic. that whole convo is hilarious.

Soilder-"Who are you guys anyways?"
Cloud-"I'm former SOLDIER first class."
Berret-"I'm from AVALANCHE"
Tiffa-"Same here!"
Aeris"I'm a flower girl from the slums...."
just find it funny they all were like pros and she's a flower girl.

Cid- "lady luck don't fail me now" (as Lady Luck airship plummets at them)

From DMC:
(final guy, can't remember name)"i'll come back!"
Dante: "and when you do give my regards to my son!"

never played this one but its from i think Phantom Blade. Apparently this beastly swordsmen gets cloned and the clone goes on a rampage
party- "what are you doing here?"
guy-"i heard i was going on a rampage so i came here to stop myself."
