All that quotes likes me a lot  but my favorites are:

"Kid, you've got the eyes of someone caught in a cold rain."-  Paul Wan

And the classic:

"Just one minute... Have any good dreams"-   Ban Midou

I love them!!!!

… Can I say the whole manga?

I’m not overreacting when I claim that I’ve never read a manga that is drawn quite like Get Backers and appeals to my personal aesthetics. I’m a girl who reads both shounen and shoujo and I appreciate both art styles for different reasons. But what Get Backers successfully does in a way I have never experienced before is the way it combines shounen with shoujo. It has the grim darkness, grit, straightforwardness and dirty lines of a shounen manga, but an equal amount of the gentle light, elegance, sparkles, dreamy picture compositon and pretty character designs clean lines of a shoujo manga. It’s an awesome art style.

Another thing I love about it is how the story is told. I mean, the way Ayamine uses angles, poses, shading, light/dark effects to enhance the feelings and atmosphere as he is trying to convey Aoki’s vision to us, the readers. He does it excellently, and a scene can be very relaxed one moment… and on the next spread you’re slapped right across your face with something you did not expect at all! Very dramatic! I also like how he adds some funny/weird details into his pictures, so even if they at a first glance seem to be drawn in his serious, beautiful style, you soon notice an ugly chibi somewhere in the background. Like here – where did that dog come from? XD Or what about Emishi’s “Look Juubei! Can you do this?”?

So yeah, pointing out my favourite pages and spreads from the manga would probably result in a too long post with too many links that you’ll need to click. Plus, I’m too lazy to find the pages online or upload them myself. XD
Do drawings from art books count? If so…

Aaaawww, look how cute they are…
A picture that is infinitely better in black and white (because there is a coloured version, and that one looks… not so good)
Ban = GB’s Mr Fanservice (seriously, looking at official GB art has convinced me that Ban hates 1) to fasten his belt and 2) wearing underwear…)
From the Divine Design arc (and I’m crossing my fingers that we’ll see Ginji in that outfit in the manga… I can dream, can I?)
G/B Badassery (from my favourite point of the manga where I liked Ayamine’s art the best)
Sleepover party! (by themselves? That must be lonely… or maybe they can have fun just the two of them, if you know what I mean)
YAAAY~!
I love their coats here (also, no unnecessary white lines that Ayamine likes to do in his coloured drawings)
Ginji and Ban in yukatas
Ginji and Ban yet again

Oh, and I’m going to include a few anime drawings as well. BECAUSE NAKAJIMA ATSUKO IS MY IDOL.

 I don’t need to actually tell you why I like this picture, do I?
A crossover with You’re Under Arrest
Hot Ban is HOT (screencap, but who cares)

This is easy:

"The S in Get Backers means neither of us is alone!"

Really, how can you not love that quote? It perfectly sums up what the GB represents; a bond that can conquer all hardships in the world.

Then there is Ban's "Just a minute!" and "Did you have a nice dream?" that go hand in hand with each other. When he says that, you know somebody just got pwned... and you as well, because you, I, we, the readers, get caught up in the illusion as well. So not only does it display Ban's wit and intelligence, but also the combined talent of Aoki and Ayamine's storytelling.

Everything that Fudou says is so much lulz. Everything. Go ahead and tell me with a straight face that lines such as "GIVE YOUR BODY TO ME! SATISFY ME DESIRES" means that Fudou wants to kill Ban, not do... another kind of physical action to him.

As for humourous lines, we have Ginji's scream of terror: "AAAAHHH!!! ....kabane-san". And who can forget the prizeless "Ginji-kun, aaah~"? XD

I'll probably come back later, so this will do for now. After all, we've got many great lines and quotes and dialoges to choose from!

I love all things Ginji, but one of the "moves" I like the most is when he plugs himself in to recover from injury.  It's not exactly a move, I suppose, but it's something he does on a regular basis!

I know this is in the manga section, but I also very much like the move Ginji does in Episode 35 of the anime, where he
Highlight to read what I wrote -- I suppose everyone's seen the anime, but I like to play it safe!   

What a good idea for a topic!  I'll see what I can come up with -- might just have to go reread some chapters so I can find my favorites again.   Such a hardship, lol!
