Leonard: Sir, uh, if I may, uh, we've put a lot of thought and effort into this current prototype. It's a really elegant solution, and most importantly, it works.
Colonel Williams: Yeah, I want this.
Howard: But that's just a theory. It's not even a complete thought.
Colonel Williams: You both make excellent points. And thank you for presenting it so articulately. Make this.

Howard: How'd you even get that up the stairs?
Sheldon: I said to myself, "I think I can, I think I can." And then I couldn't, so I paid two men who promised not to come rob us later.

Colonel Williams: What's this?
Leonard: Oh, nothing. Just some math we don't need.
Colonel Williams: This is a different approach. Are you trying to get the guidance system even smaller?
Leonard: It's just a theory. Uh, it's not even worked out.
Colonel Williams: Oh. I want this.
Howard: But we've already met the agreed upon specs. Going smaller would require weeks' worth of new computations.
Colonel Williams: So get the kid with the two shirts to do it.

Leonard: You know, I do have a way to get him out of our hair. I've been holding onto this for a few years, but maybe now's the time.
Howard: We can just lock the door; you don't have to kill him.
Leonard: You can't kill him; he'll just respawn at the last save point.
