Stargate Atlantis, Season 2

[After Zelenka realizes Sheppard wants him to go underwater in the puddlejumper with him to save McKay]

Dr. Zelenka:
Oh! No-no-no-no-no-no - I cannot possibly ... uh, no.

Dr. Weir:
Radek.

Dr. Zelenka:
I-I ... I can't even swim!

Lt. Col. Sheppard:
There's not a lot of swimming under a thousand feet of ocean.

Dr. Weir:
(to Radek) Look, I'm not gonna order you to go.

Lt. Col. Sheppard:
I will! [Elizabeth shoots him a look]

Dr. Weir:
All I'm saying is that if Rodney can't turn to you, who can he turn to?

Dr. Zelenka:
[thinks for several seconds] Right. Give me a few minutes and I'll get my gear.
