By my calculations (wild speculation) every person on Earth will have been dared to accept the ALS Ice Bucket Challenge by the end of the month. But even a galaxy far, far away was been tapped to help it seems.

Enter R2-D2. Despite being a droid, an existence highly allergic to water, everyone's favorite mechanical sidekick accepted the challenge from some sadistic Facebook friend who secretly hates him. R2 challenges Anthony Daniels and Grant Imahara.

Side note: Anyone else creeped out that they used another R2 unit's head to pour the water on Artoo? No? Okay then.
