What are your favourite quotes from WALL•E? Mine would be:
“Got too much garbage in your face? There’s plenty of space out in space!” – BnL billboard.
“Stupid wheel!” – Captain.
WALL•E: “Dirrrr-ect-tivvve?”
EVE: “Directive?”
[WALL•E nods]
EVE: “Classified.”
WALL.E: “Oh.”
“You look gorgeous!” – P-RT.
EVE’s Laugh… lol
My favorite quote:
Captain: Look what I got Auto!
Auto: Not possible
Captain: Hahahahaha that’s right! The plant! You want it? Come and get it blinky!
scanning…
“100% Foreign Contaminant!”
M-O : “Whoa, whoa, whoa, whoa, whoa!”
Aside from WALL-E and EVE generally saying each other’s names (it never gets old!), these are my favourite quotes-
‘Captain…?’- Just the way AUTO says it, rather than what he’s actually saying, makes me love him.
Mary- ‘John, get ready to have some kids!’
Captain- ‘Define hoe-down.’ (This one always gets me laughing. 
)
“Wall-E.”
“M-O.”
“…M-O?”
“M-O.”
“…M-O.”
“I didn’t know we had a pool!” - Mary
“We have a jogging track?” - The Captain
I love when EVE say’s Wall-E for the first time in the seductive voice and he falls to pieces
Captain- “Well, good morning everybody and welcome to day 255,642 aboard the Axiom…this is our 700th anniversary of our 5 year cruise.”
Shelby Forthright- “Because at BnL, space is the final fun-tier!”
Auto- “Aye, aye, sir.”
I like the dialog between Wall-e and M-o 
it is funny, mostly because of the way M-o looks and moves.
I do not know the exact quotes cuz I have seen Wall-e translated, but I also liked Captain saying in the end: ‘This is called farming. You can grow various plants - vegetable plants, fruit plants, pizza plants - oh, how good it is to be home!’
Wow, you guys have covered most of the speech already xD.
My favorite:
“Too much garbage in your face?
There’s plenty of space out in space!”
and
MO: “AHHHHHHHHHHH”
Oh! Yeah, I love that one too! 
I know it’s not a quote, as such, but I love the little squeaks and chirps Hal makes. For a character so completely unhuman, it’s amazing how Pixar have managed to give him his own little personality too.
“Yay, jippiti jah!” — John.
“Define ‘hoe-down’” — Captain.
I also like it when Shelby Forthright says “By golly, we can begin Operation Recolonize” and “Let’s get the heck out of here”. Just that sort of censored language makes me laugh. And the finger quotes he does: “EVE probe” are just so great, too.
“Don’t forget to get your free Septuacentenial cupcake in a cup.”
“Mmm, time for lunch… In a cup!”
“Attention Axiom shoppers, try BLUE! It’s the new red!”
And the first time EVE says “Wall-e”.
“Name?”
“Wua-wuaaaleee”
“Wall-E”
“Aww”
also
“Uh”
“Uh”
Captain: Where’s the thingy?
Auto: Plant.
Captain: Yeah the plant. Well where is it? Maybe we missed a step…
Captain: Operate, Manuel.
McCrea: “I don’t WANT to survive! I want to LIVE!”
“…We have to go back.”
Also, not really a quote, but the face McCrea gives Auto after he says “That’s an order!” makes me crack up every time.
This is some beautiful dialogue right here…
Captain: AUTO, things have changed! We’ve gotta go back!
AUTO: Sir, orders are: “Do not return to Earth.”
Captain: But life is sustainable now! Look at this plant: green and growing. It’s living proof he was wrong!
AUTO: Irrelevant, Captain.
Captain: What?! It’s completely relevant! Out there is our home… home, AUTO; and it’s in trouble. I can’t just sit here and… and do nothing! That’s all I’ve ever done! That’s all anyone on this blasted ship has ever done!!! Nothing!!!
AUTO: On the Axiom, we will survive.
Captain: I don’t want to survive… I want to live!!!
AUTO: Must follow my directive…
Most of this is stuff that’s already been posted, but I just crack up over the corny lines in the video WALL•E passes on the way to his truck…
“Too much garbage in your face?
There’s plenty of space out in space!
BnL Starliners leaving each day…
We’ll clean up the mess while you’re away!”
Mary: Hey! Hey, that’s what’s-his-name…!!!
(I’m not sure why I find that funny… 
)
Nanny Bot: A is for Axiom, your home sweet home. B is for Buy ‘N’ Large, your very best friend.
(My sister and I are in the process of working on the entire alphabet. We can’t think of ones for “X” and “Z”… 
)
And that beeping noise M-O makes in one of the first scenes after WALL•E goes off to chase EVE when she’s being taken to the Bridge… it’s the one he makes right before he decides to jump off the track. It sounds like he’s cussing or something…! 
Get Ready to have Kids!
Actually I kinda like the BnL jingle, which has gotten stuck in my head more than once: “Buy and Large, the superstore, all you need, and so much more!”
