Shampoo or liquid soap dispensers, or "soakies," have been popular in the U.K. for awhile. They say that, while writing Star Wars, George Lucas fantasized about someday creating mugs made to look like R2-D2. For some reason, I doubt he had soakies in mind too. But that doesn't make these any less fun. That cheesy image of Vader in the upper left corner is a classic.
