"It's so stupid," Stella told Marshall. "I mean, first of all, how do they understand that walking bear they hang out with all the time?"
"Wookie," Marshall said, sadly.
"Yeah," she said. "He goes, 'Hmmmm,' (doing her best Chewbacca impression), and they're all, like, 'that's a good point, bear! Let's try that.'"
Now don't me wrong, I geek out as much as anyone when the opening crawl rolls, but she has a point. How does Han Solo possibly understand what Chewbacca is saying? It's like me understanding the moans, grunts, growls and barks of my dog. Even the nerdiest dweebs must admit this major flaw in the story. Though I am prepared for the rebuttal.
