I've always liked the idea and use of pneumatic tube systems to transport things. There's something about the lo-tech air powered technology zipping information back and forth that endears them to me. Anyway, they are also one of the many reasons that I like this Hula Hoop segment from the Hudsucker Proxy so much.
Here's one other movie clip where the pneumatic tube steals the scene : http://www.youtube.com/watch?v=YLEJbFKTyQI
