Stargate Atlantis, Season 5

Dr. McKay and Beckett are in a holding cell.

Dr. McKay:
I've got lots of experience escaping from these things.

Beckett:
You do?

Dr. McKay:
Oh, yeah, yeah. Been in this situation dozens of times, always figured a way out.

Beckett:
How, exactly?

Dr. McKay:
Ah, let's see. Uh, last time, Teyla was posing as a Queen, so, um... you know, she had us released.

Beckett:
Not much chance of that happening.

Dr. McKay:
No, I guess not.

Beckett:
How about the time before that?

Dr. McKay:
Ronon's friend Tyre was pretending to be in league with the Wraith but really he was on our side so... he let us out.

Beckett:
I'm startin' to sense a pattern here. You've actually never really escaped from one of these cells on your own, have you?

Dr. McKay:
First time for everything, right?
