Because if Chewie lived in NYC, he'd obviously be a stand-up comedian.

I'm serious: Chewbacca would totally be going up at the Comedy Store. Just look at the things that drive people (and Wookies?) to become stand-ups. Being a little bit different than everyone you're around helps, and when do we ever see other Wookiees in the original Star Wars trilogy? Getting shit on at your job helps fuel stand-up too, and Chewie gets treated more as Han's sidekick than an equal. And aren't many people driven to perform stand-up because they feel like other people don't understand them? As far as I know, most people don't speak any Shyriiwook, Thykarann, or Xaczik (the three Wookiee languages, duh).
