Here are *some* more of my favorites...
"Father said she went to a beautiful place, where everything is peaceful, and everyone loves each other, and no one ever gets sick. Do you think there's really a place like that?" -- Gia
"Yes... I do." -- Data (Thine Own Self)
"Legends. . . are the spice of the universe, Mr. Data, because they have a way of sometimes coming true." -- Captain Picard (Haven)
(Here is one of my top favorite quotes; I use it in my signature image...)
"If being human is not simply a matter of being born flesh and blood- if it is instead a way of thinking, acting, and feeling- then I am hopeful that one day I will discover my own humanity. Until then, Commander Maddox, I will continue learning, changing, growing, and trying to become more than what I am." ~ Data (Data's Day)
Chief O'Brien: "We'll all be burning a midnight-oil on this one."
Data: [turns and calls as he walks on by] "That would be inadvisable."
Chief O'Brien: "Excuse me?"
Data: [walks back] "If you intend to ignite a petrolium product on this ship at zero-hundred hours, you will activate the fire suppression system, which would seal off this entire compartment."
Chief O'Brien: "That was just an expression."
Data: "Expression of what?" -- (All Good Things)
Picard: "What the hell is going on?"
Data: "There appears to be condensed suspension of water-vapor. Approximately one degrees Celsius."
Riker: "It just sort of rolled in on us, sir." -- (Sub Rosa)
Riker: [sad and quiet] "It's just that... our mental pathways have become accustomed to your sensory input patterns."
Data: "I understand. I am also fond of you, Commander. And you as well, Counselor."
-- (Time's Arrow)
Data: "Spot. Spot. Spot! Down. Spot! Down. Down! [sighs; picks up Spot, kneels down by the floor and points to it] Spot. Down. This is down; down is good. [raises her up to the console] This is up; up is no."
-- (Force of Nature)
Data: "Unfortunately, I have been less than successful [at training Spot]."
Geordi: "I've got an idea. How about a phaser ? A low stun-setting at just the right moment might do the trick!"
Data: "Geordi, I can not stun my cat."
Geordit: "... I was kidding, Data."
-- (Force of Nature)
Data: "I noticed that many spectators seemed distracted during my presentation. Was my poetry uninteresting?"
Geordi: "Well, it was... very well constructed. Virtual tribute to... form."
Data: "Thank you. And...?"
"It is interesting that people try to find meaningful patterns in things that are essentially random. I have noticed that the images they perceive sometimes suggest what they are thinking about at that particular moment. Besides, [the star cluster] is clearly a bunny-rabbit."
-- Data to Guinan (Imaginary Friend)
[Data performs a Vulcan nerve-pinch on Sela.]
Spock: "Not bad."
-- (Unification - Part II)
Data: "A conflict has arisen between the planetary evolution team and the stellar physicists. Each wishes to be the first to use the thermal imaging array."
Geordi: "Well, tell them to flip a coin. We got to work together on this mission or otherwise we'll never get it done."
Data: "A coin. Very well, I will replicate one immediately."
-- (The Game)
Data: [his face and one eye scrunch up] "That is not the correct port."
Riker: "Sorry." [pokes around more and Data's face abruptly returns to normal]
Data: "You must hurry, Commander; the containment field has dropped to 16%."
Riker: "I am trying! You need a bigger head."
"It is true that the intellectual efficiency of higher order beings does diminish proportionally with the deprevation of nutritious fuel and. . ."
--(Half A Life)
Dr. Beverly Crusher: "You are worried about Geordi, aren't you?"
Data: "I am an android. It is not possible for me-- "
Beverly: "--to feel anxiety."
Data: "Starfleet personnel have vanished. Others may be at risk. We must do the best we can to find out why."
Beverly: [just looks knowingly] "Krhm."
Data: [pausing, and glancing sideways at her] "However, I am... strongly motivated... to solve this mystery."
-- (Identity Crisis)
Riker: [sarcastic] "What? No seconds?"
Data: "I have discovered, sir, a certain level of impatience when I calculate a lengthy time interval to the nearest second. However, if you wish... "
-- (The Loss)
Data: "On the captain's command, we will fire 4 photon torpedoes directly at the Hathaway. One millisecond after its detonation, the computer will trigger your warp jump."
Geordi: "I think I hate this plan. Data, we are not even sure our warp jump will work."
Data: "If the warp engines fail to function, the result could be... unfortunate."
Worf: "Very unfortunate. We will be dead."
-- (Peak Performance)
"If there's nothing wrong with ME... maybe there's something wrong with the universe."
~ Dr. Beverly Crusher (Remember Me)
Picard: "Didn't *anybody* here build ships in bottles when they were boys?"
Worf: "I did not play with toys."
Data: "I was never a boy."
O'Brien: "I did, sir!"
Picard: "Thank you, Mr. O'Brien... proceed."
-- (Booby Trap)
Data: "Captain, I am detecting life readings from the planet surface... as well as several small areas of thermal radiation and carbondioxide emissions indicative of combustion."
Wesley: "Camp fires, Data."
Data: "Is that not what I said ?"
-- (The Vengeance Factor)
Q: "This is incredible."
Geordi: "You see something here, Q?"
Q: "I think I just hurt my back. I'm feeling pain. I don't like it. Uh, what's the right thing to say? 'Ow'?"
Data and Geordi in unison: "Ow."
Q: "OW!! I can't straighten up!"
-- (Deja Q)
"There are creatures in the universe who would consider you the ultimate achievement, android. No feelings, no emotions, no pain. And yet you covet those qualities of humanity. Believe me, you are missing nothing. But if it means anything to you, you're a better human than I."
-- (Deja Q)
"Lal is my child. You ask that I volunteer to give her up. I cannot. It would violate every lesson I have learned about human parenting. I have brought a new life into this world and it is my duty, not Starfleet's, to guide her through these difficult steps to maturity. To support her as she learns. To prepare her to be a contributing member of society. No one can relieve me from that obligation. And I cannot ignore it. I am... her father."
-- Data (The Offspring)
(((And I will just thrown in this movie quote for kicks, because I love it...)))
Data: "I feel obliged to point out that the environmental anomalies may have stimulated certain rebellious instincts common to youth, which could affect everyone's judgement... except mine, of course."
Beverly Crusher: "Okay, Data, what do you think we should do?"
Data: "Saddle up; lock and load!" -- Star Trek: Insurrection
