Most of the System Lords were killed by the Replicators. Then, we defeated the Replicators.
Wow, we look cool.
Don't let it go to your head.

Lieutenant Colonel Cameron Mitchell, leader of SG-1.
You are not...
Will he be here?
Now, considering their unique ability to maintain an active Stargate indefinitely and their force field capabilities, the President has authorized any and all means to complete the mission.
Oh, boy. And here I was trying to have a nuke free career.
[Mitchell, Carter, Daniel, and Teal'c set off on their first mission together, with Vala]
How good is this? Got the band back together!
[looking at Vala] Yeah, so what's with the extra back-up singer?
Oh, she's good fun.
[pulling Vala's scarf off her neck] Vala, this is a military vessel.
I know, darling. I've stolen it before.
Well, just try to be, uh…
My charming self?
Just a little less talk; a little more shut the hell up.
The next idea we come up with has to be outside the box.
Okay, the gate is composed of individual units. The—There must be some sort of energy linkage between them, like a—like a chain.
Exactly, so we—
So we need a big ol' set of bolt cutters.
Oooh. Too far outside the box. Get closer to the box.
GUGoa'uld Nerus
I have helped the Ori, and when you kill me, I shall ascend.
No, you will descend to a small, dark room at the bottom of Area 51, and you stay there until you come up with a way to defeat the Ori.
What could possibly compel me to do that?
General Landry (Smiling in satisfaction):Hunger.

S9 E7Ex Deus Machina
Witnesses?
One. Some guy who was working overtime, spent most of the firefight under his desk, but was able to provide the descriptions of three individuals: big, tattooed, chain mail pants.
So it's either our Jaffa, or KISS is back on tour.

[imitating Teal'c] "The Warriors of the Sodan exist, Colonel Mitchell. I am certain of it."
Needs more bass.
Receiving an IDC, sir. It's Colonel Mitchell.
You're kidding.
I would never do that, sir.
VVolnek
Oh, we have unfinished business.
Hey, take it easy.
VVolnek
You shot me!
You shot me first!
JJolam
You are not tired?
Six weeks' airborne training at Fort Benning-- that's tired. This is nothing. Come on.
S9 E9Prototype
[Carter realizes why the Stargate is malfunctioning]
Huh. Maybe it wasn't our fault.
I thought it was always our fault.
[SG-1 is exploring an abandoned Goa'uld lab]
[approaching weird technology] There is someone home.
Wa-wait!
[touches button] What? I was looking for the light switch.
[shining his flashlight at Mitchell] New guy!
[indicating a computer] Hey, you touched that!
Ah, I know how to read that!
[Regarding Khalek]
I shot him twice point blank.
And he's healing. Remarkably fast.
I should have emptied the clip.
