Those marked with a * came from movies, TV, t-shirts, and other people I don't know. The rest were actually said by people around me. i.e. "Luna" and "Serena" are friends of mine, not the Sailor Moon characters. :)
Luna, as Quina: "Kuja....you have feathers on head like turkey. Maybe I can....cook you? You white like yum-yum vanilla ice cream! I eat you!"
Me: "This burger is falling apart like the Russian parliament."
*Steve King (in "Monkey Bone"): "Bite me, Poe!"
Fuu: "Okay, I have a test to see if you're cool enough to hang out with us. Do you like 'The Princess Bride'?"
Tony: "I think watching it with friends is an insane bucketload of fun."
Luna: "Do you think if we poke it, it'll come alive?"
Me: "Start making sense, you whore!"
Luna: "Whores aren't supposed to make cents, they're supposed to make dollars."
Magus: "My symbiote just loves peanut butter."
Me: "So I guess this is the Hunt for Orange in October."
some guy: "Don't skeen the weelie!"
???: "Is it cheating if it requires peanut butter?"
Magus: "Quit eating Chibi Moon!"
Mr. H: "Guys, you're missing the point. It's not about nipples."
Me: "I mean, would you want to hear Mr. Rogers talking about nipples?"
Averiah: "He dropped his pencil. It fell to the table like a Satan coming out of Hell!"
Luna: "Do you have any Froot Loops?"
Jane: "Happy aliens are not innocent."
Averiah: "I can see your shoulder. [Luna] must not be here!"
Jane: "Just because we smoke and do drugs and kill people doesn't mean we're freaks."
Brian: "Jesus is the kind of guy who would skip school to go preach somewhere."
Bill: "I'm not Jesus."
Brian: "That's what I said!"
Nigel: "Stop acting like a diseased chipmunk!"
Luna: "How come people like to be spanked but not hit in the arm?"
*Voltaire: "How do you get a goth out of a tree? ... Cut the rope!"
Luna: "I found you, your crunchiness!"
Magus: "Now, for my next trick, I'll make your chest disappear!"
Bill: "No one said you had to eat them, you sick bastard. You just have to skin them and write on their flesh."
Luna: "Your pants smell. Take them off."
Mina: "How come [Magenta] always gets to be the gay one? Why can't I be gay once in a while?"
Averiah: "Sticks and stones may break my bones, but whips and chains excite me."
Kitty: "Who needs a man when you've got a bird?"
*Jay: "The whole fucking world's against us, I swear to God."
Serena: "Don't you be dissin' my thingee!"
Serena: "You want to make me call you a ho?"
Me: "What if they were that big in real life?"
Ruth: "You're just like Hitler! You're mean!"
Kitty: "Your Mom!"
Bill: "Oh, you're gonna throw your hat into the fetal panther ring?"
Luna: "Drive-bi shounen!"
Tellu: "I had a dream that the president got shot and I woke up laughin'."
Kelly: "That's my angry sneeze."
Bill: "It's non-productive at all!"
Averiah: "I'm such a bastard. I don't deserve my dog. He's so cute."
*bumper sticker: "Support Cannibalism... Eat Me!"
Magus: "Who do you love, baby?"
Magus: "Get a room!"
Me: "With who?"
Magus: "Langly."
Me: (*staring blankly into space, thinking...*)
Me: "It's just like Seifer. I've never played FFVIII, but I know about him."
Luna: "Yeah, because Magus always shoves it up your ass. ... No, no! I meant to say your face, but your ass popped out!"
Mina: "I've had bigger."
Raul: "I have full concentration in myself."
Bill: "What if your sociopathic boyfriend had a sex change?"
Me: (*staring blankly into space once again, deep in thought*)
Bill: "You're thinking about that way too much."
*can't remember the name of this character but she's from a movie called 'Cecil B. Demented': "Hey, hey, MPAA, how many movies did you censor today?"
*see above: "You're so pale... Satan says you need more color!"
Mom: "I just love your nail polish. It goes perfectly with your salad."
*some t-shirt: "I'm not playing with myself, I'm adjusting my jewelry."
Sarge: "I never like to end a relationship because give me back my Milky Way!"
Luna: "Floating dyke at 1:00!"
Averiah: "I laid eggs in your head!"
Magus: "It's full of Mormon-burnin' goodness!"
Me: "You didn't turn it in? You're fooked."
Luna: "That sounds like fun. I think I'll have some."
Luna: "I have a cetacean stuck in my nose, mommy, what's stuck in yours?"
Me: "Quit poking my liver!"
Magus: "Screw brainsaving! It didn't work for Hitler and it's not gonna work for you!"
Me: "Life apparently thinks I have something better to do than cannibalistic death orgies."
Magus: "Your nose doesn't taste like chicken."
Magus: "You can take my pants, but you can never take my freedom!"
Me: "Time flies when you're not pondering slitting your wrists."
*Mandi: "Dreams fill the cracks which reality creates."
Me: "I bet it's that damned marker. You heard how it smelled."
Luna: "What if they can't read?"
Me: "Then they won't know where to poke."
Me: "You don't know where that knee's been!"
some guy in my drawing class: "How did Pinocchio find out he was made of wood? ... His hand caught on fire."
my drawing teacher: "The only ones who should say 'we' are kings, senators, and people with tapeworms."
Me: "Are you saying he's going to sleep with my camera?"
*Mark Sumanski: "Do you know the difference between oral sex and a hamburger?"
some Jamacian chick: "Well, I have a feeling you're going to tell me."
Mark Sumanski: "Oh, I was just wondering what you're doing for lunch..."
a guy in my drawing class: "A shark walks into a bar. Bartender asks him 'What can I get you?' Shark says 'Nothing, I'm just here for the hell of it.'"
