Quotes / Replacement Goldfish

Michael: You BASTARD! I set Edgar free in the middle of the video and Ryan led him back!
Ryan: […] I went and fucking grew wheat and led a cow back—
Geoff: You grew wheat!
Michael: Wait, wait, did you get Edgar back?
Ryan: I dunno.
Michael: You just got a random cow, so as far as we know he's free in the wild—
Geoff: He doesn't give a fuck which cow it is.
Ryan: Yeah, Edgar is—
Michael: Of course it matters! That was the original Edgar!
Ryan: No, you don't understand: "Edgar" is the one in the hole.

Tycho: Yeah.

Tycho: It really wasn't a good investment.

Church: Washington?! Why are you wearing Blue armor? ...Why are you wearing my armor?
Wash: Oh. Um...
Caboose: Oh, yeah, yeah.
Wash: They sorta used me to... replace you? On Blue team?
Church: Replace me?
Caboose: I wouldn't really use the word "replace", but there's no word for "take over for you and make everything better almost immediately". So we just say "replace".
Church: When did this happen? [...] Right after I left?!
Caboose: Well, it wasn't right after, but, y'know, but, it was like… five, ten seconds.
Church: You've gotta be kidding me.
Caboose: Life is short. We had to move on.
Church: I think I just got dumped by Caboose. This is un-fucking-believable!
Caboose: Yeah, it's not me. It's you. [...] Oh, um… we sorta call the new guy "Church," y'know, sometimes?
Church: What.
Wash: Caboose just finds it easier. The armor color confuses him... As do a lot of things.
Church: Let me get this straight, Agent Washington. You took my NAME, too?
Wash: It's only in certain circumstances.
Caboose: Like when we talk to him. Or when we fill out paperwork. Or sing Happy Birthday to him.

This is fish number six hundred and forty-one in a lifetime of a goldfish. My parents bought me the first one to teach me about loving and caring for another living breathing creature of God. Six hundred and forty fish later, the only thing I know is everything you love will die. The first time you meet that someone special, you can count on them one day being dead and in the ground.

Kerchak: Kala, it will not replace the one we lost.
Kala: I know, but… he needs me.

In a glen beyond the castle wall
There was a tinker
And he was a thinker
The smartest man in all the world
He made a mechanical girl
For you see, his daughter passed away that summer
And though he knew he could not replace her
He missed his family
Voltaire, "The Mechanical Girl"

What am I, some sort of Gadolt substitute!?

Sam: Good ol' Mr. Spatula. The exact same Mr. Spatula we've always had. Certainly not just some other fish we've been calling Mr. Spatula ever since we found the original floating belly up in this very water cooler just last week.
Max: Careful, Sam. Keep it up, and he might realize he's just... a replacement fish!
