I'm not sure how to transcribe R2D2 noises.....anyways.....if you can knit (or have a friend whom knits, or can hunt down someone whom knits, etc.) you can have an R2D2 beanie (or toque if you're Canadian). I can knit and have been meaning to make this but haven't gotten around to it, but the pattern is free online at Carissa Knits. People have commented that it wasn't difficult to make and the pattern is ready in three sizes (child, adult small, and adult large). The supplies you'd have to buy end up being enough for two so you and your BFF can have matching hats (toques) and run around beeping at each other pretending to understand what's going on! Or at least that's what I would do....and will do when I get around to making this!
