Stargate Atlantis Season 4 Episode 13

(The self-destruct alarm has gone off. Ronon and Doctor Keller are in the Infirmary. Ronon is trying to get the door open)
Keller: Ronon, we've already tried. It's not gonna open!
Ronon: We'll just have to blast a hole in it!
Keller: With what? You don't have your gun.
Ronon: Got any C4 in here?
Keller: In the Infirmary?
Ronon: Anything we can use to act as an explosive?
Keller: I don't know, I...er...the oxygen tanks, maybe?
Ronon: Right...like Sheriff Brody did in that movie...Jaws!
Keller: Yeah, I know, I've seen it. What are you...?
(Picks up an oxygen tank)
Ronon: Alright, all we need is a gun to shoot it with. You got one in here?
Keller: Again, Infirmary, not armory.
