You're not going to believe this but there is actually a R2-D2 soy sauce serving bottle coming out in Japan. Now who in their right mind would want an Astromech droid leaking brown fluid onto their food? I'm still a little disturbed by it really. Just click the pics to check it out.
If you're interested in ordering one check out this website. There's even an R2-Q5 version, woohoo!
