Oh, that was just an AWESOME scene! One of my two favorite scenes in the movie -- the other one being the conversation in the shuttle where Sigourney Weaver's character is trying to convince "Guy" that he's not expendable because he really does have a last name.

It was just such an awesome, gigantic sci-fi in-joke. Obviously made by SF fans, for SF fans.

"Let's get out of here before one of those things kills Guy!"
