You know the drill. Best caption wins eternal fame and glory.
Just as a request, if you're going to caption something Chewie is saying, please translate it to English (Or Galactic Basic, I guess), unless you have a brilliant way of transcribing in letters or numbers the noise that Wookiees make (Shyriiwook is the name of their language, apparently).
Also, thanks to Wikipedia (and Star Wars Fanboys) for this: "Shyriiwook (also called Wookiee Speak, or contracted as "Wookieespeak" in the Expanded Universe, and video games) is the native language of the Wookiee race. They also speak xyro. The language consists of roars and growls. Although it can be understood by members of other species, it is extremely difficult for those with non-Wookiee physiology to speak. Conversely, Wookiee mouthparts physically cannot create the sounds of Galactic Basic, thus while Wookiees such as Chewbacca can understand characters speaking Basic, he cannot speak it. In Timothy Zahn's "Heir to the Empire", Leia Organa Solo encounters a Wookiee with a speech impediment which conveniently renders his Shyriiwook pronunciation much easier to understand by Leia. Another Wookiee language, Xaczik, is indigenous to Wartaki Island on Kashyyyk and several outlying coastal regions."
