Single Best Sci-Fi Television Moment . . . EVAR!?

[Rackhir]

There was a scene during "Shattered Dreams" when there was a crippled Starfury that was spinning in on on B5's bridge with the point defense guns reaching out for it in spirals. I was so into the scene that I was a hair's breadth away from leaping behind the couch to protect myself from it.

Hmm...hard question, I've got a few. My all time fave would have to be from B5, Ivanova's "God sent me speech" gets me every time. the Zog yes or no bit was pretty priceless as well.


Farscape Peace Keeper wars, the D'Argo bit at the end (you know the one I am talking about) "Who's your daddy!? Who's your daddy!?" Awesome stuff. Well, actually any time D'Argo got into the who's your daddy thing with Chricton kills me.

Firefly-the funeral scene in 'The Messenger' gets me every time.

ST:TNG - On top of the others already mentioned: The Inner Light, the whole episode, Family the whole episode, Measure of a Man when Picard realizes what the trial really is about and for pure humor, nothing beats Worf teaching Wesley about Klingon mating rituals in The Dauphin. I crack up just thinking about it. "No, the women screams... *dreamily* and throws large objects!"s

Kirk preventing McCoy from saving Edith Keeler in "The City on the Edge of Forever"

Exactly what I thought when I read the title of the thread.

McCoy: Do you know what you've done?
Spock: He knows, Doctor. He knows.

Wow. Fantastic episode all around, but that part just gets me.

My favorite moment, too. And I hate Star Trek.

I think that episode started my love of time travel stories. I also really like the end of the "A Stitch in Time" Outer Limits episode, when the FBI agent (Michelle Forbes) goes back in time just one more time....

One (if not _the_) favourite Farscape (funny) moment is in the 3-parter Look at the Princess (Paraphrasing
D'argo: "John, I have a good and a bad message for you."
John: "The bad one first."
D'argo: "You will be painfully transformed into stone for 50 arns, and when you come back all your friends and family will be dead."
John: "And the good one?"
D'argo: "Chiana and I are having great sex."
...

I really love that scene - Look at the Princess is probably my favourite Farscape episode..

 

[Vigilance]

Angel: "Hey, Wes, did the devil ever make a robot?"
Wesley (awestruck): "El Diablo Robotico"

My favourite scene in television sci-fi history:

Captain John Sheridan: May I have your attention please? In the last few hours, we have learned that warships are coming this way from Earth. Their orders are to seize command of Babylon 5 by force. As commanding officer and military governor of Babylon 5, I cannot allow this to happen. President Clark has violated the Earth Alliance Constitution: by dissolving the Senate, declaring martial law, and *personally* ordering the bombing of civilian targets on the Mars colony. He is *personally* responsible for the deaths of hundreds of innocent people. Following these attacks, Orion 7 and Proxima 3 have broken away from the Earth Alliance, and declared independence. Babylon 5 now joins with them. As of this moment, Babylon 5 is seceeding from the Earth Alliance. We will remain an independent state till President Clark is removed from office. At the end of this current crisis, anyone who wishes to leave for Earth is free to do so. Meanwhile for your own safety, I urge everyone to stay in your quarters until this is over. That is all.

Sends a chill up my spine everytime I watch that scene, or just hear it on mp3.

And for most the humourous moments in sci-fi here's Ivanova!

Susan Ivanova: Ambassador, do you really want to know what's going on down there?
Ambassador Londo Mollari: Yes, absolutely!
Susan Ivanova: Boom. Boom boom boom. Boom boom. Boom! Have a nice day!

Susan Ivanova: Vakar Ashok, our gun arrays are now fixed on your ship and will fire the instant you come into range. You will find their power quite impressive... for a few seconds.

Susan Ivanova: Worst case of testosterone poisoning I have ever seen.

Susan Ivanova: It's just that I've always had trouble waking up when it is dark outside.
Commander Jeffrey David Sinclair: Commander, we're on a space station. It is always dark outside.
Susan Ivanova: [forlornly] I know... I know..

Susan Ivanova: This isn't some deep space franchise, this station is *about* something!

Susan Ivanova: Good luck, captain. I think you're about to go where... everyone has gone before.

Major Lianna Kemmer: I demand you open a channel to Earth at once.
Susan Ivanova: I'm a Lieutenant Commander on Earth Force, Major. I don't take demands. If you will request, I will consider it.
Major Lianna Kemmer: Very well, then. I request that you open a channel to Earthdome.
Susan Ivanova: Request denied. Have a nice day.

Season 5 just was not the same without her...

 

[Zog]

the Zog yes or no bit was pretty priceless as well.

Yes. Yes it was.

My first thought was Delann's 'Why Not?' speech in Shattered Dreams.

Second thought was the Buffy Finale - Series 7, the horde rushing the Slayers, the 'Everyone who can stand up, will stand up' speech. Great stuff. And for TV? Fantastic!

All 40+ minutes of Sleeping in Light. Just so poignant.

Plus:
"At least I could have boffed him once!"
"Did you say Boff?"

Made even better by the naming of the dead ships as they passed through the graveyard.

What really got me about that scene was that one of the ships they name is the ship that Riker had been offered the captaincy of in the previous episode. That was a shock.
