In this episode, in the nightclub, Stu contacts Didi using his new satellite phone. And it's not any satellite phone -- it's the "Pickles Ultimate Satellite System", or "PUSS". Unlike traditional cellular phones (where you must be within a certain distance from a cellular antenna), satellite phones can be used almost anywhere on earth, as long as the phone "sees" the satellite. However, satellite phones, and their calling plans, can be quite expensive. And of course, you often have to buy your own equipment from the provider, not jerry-rig one up yourself (like Stu's). Just as well, though -- Stu's satellite phone doesn't work well.
