Either R2D2 has an oil leak, or the Japanese have some crazy ideas about combining soy sauce dispensers and Star Wars droids.  As the Tokyo Mango says, "The picture makes it look like he’s barfing brown goo onto the earth."  I guess R2 got ahold of some bad sashimi, or maybe he just watched Episode 1 again and was reminded of the horrible things George Lucas has done with what used to be a great trilogy. 

Get one here, if for some reason you eat a ton of soy sauce on all your meals and have a dining room that looks like the conference room on the Death Star.  Soy sauce is much more appetizing when it leaks out of a mechanical device.  All sauces are, really; that’s why my car is lubricated with delicious Hidden Valley Ranch salad dressing.
