Gonk

Haha, a gonk droid!  You had C-3PO who could talk, in over six million languages no less, you have R2-D2 who could beep and whistle and then you had the Gonk droid who could only say "gonk".  I don't get it.  Still though they are actually called GNK power droids and are a power generators that only understand basic commands and are usually only used on under-developed worlds.  I know you guys already knew that, especially Cara because she's a big Star Trek fan.
