Church: Me and Tucker will go through the teleporter, and cut him off at the pass! Tucker, you ready?
Tucker: There is no way I'm going through that thing.

Tucker: I don't know! Why would they give us a tank that nobody could drive?
Church: We already tested the teleporter, remember?
Tucker: We threw rocks through it!
Church: And? So? The rocks came out the other side, didn't they?
Tucker: Yeah, but they were all hot, and covered in black stuff.
Church: So this is what this is all about - you're afraid of a little black stuff.
Tucker: Yes, I am. I am afraid of black stuff.
