From Thinkgeek:

This set of R2-D2 Measuring Cups disassembles into 4 measuring cups plus 4 measuring spoons and reassembles in a snap (fortunately, it’s not as complicated as C-3PO). Each has its measurement written inside so you can’t forget what they are and handles on the back that don’t distract from R2’s aesthetic. The only problem we can foresee with these is that if you show somebody else your R2-D2 Measuring Cups, you may have to install a restraining bolt to keep them from wandering off.
