McKay: How about we say goodbye now.
McKay: What do you mean no?
Sheppard: I mean, I'm not saying goodbye.
McKay: Well I'm saying it anyway.
Sheppard: Well, I'm not listening.
McKay: Pretty soon I won't know who you are.
Sheppard: Then I'll remind you.
McKay: Yeah, but I don't want you to see me like that. I want you to remember me as I am, as your genius friend. Not as some…
Sheppard: Not happening.
Sheppard: You're stuck with me, Rodney. Just accept it.
Sheppard: No. That's final.
McKay: You've been a good friend, Arthur.
(They look at each other and burst out laughing)
