Tim: I'd still like to help you build it.
Wilson: Great.
Tim: All right! Well, I'd better get these lights down and back. Tool Time set's kind of dark without them.
Wilson: You need some help?
Tim: No, I'll get them... Hey! Are any of those reflectors parabolic?
Wilson: Well, yes. Why?
Tim: I've got an idea of some fun we can have a little later on tonight.
