The night was dark and gloomy. Han and Chewbacca boarded the Millenium Falcon under the cover of night so that no one could see them. This was an important mission; one that no one must know about. If anyone found out it would be most embarrassing for the two of them. This was no ordinary assignment. No. Chewbacca was going for speech therapy to cure his speech impediment.
To anyone who cannot understand Shyriiwook, Chewbacca's speech impediment is not noticeable. When Chewbacca speaks to Shyriiwook speakers, both native and otherwise, Chewbacca's pronounciations were becoming increasingly difficult to understand. He needed therapy at once! He could not afford a droid to do the talking for him. They were already severely in debt to Jabba The Hutt.
Before anyone realized the Falcon was missing, they were at top speed, zooming through the night. For the first half hour they travelled in silence. Then Chewbacca spoke.
"Graaaaah!"
Han paused for a moment trying to figure out what exactly he said. Chewbacca tried again.
"Graaaaaah!"
Han paused again. "I'm sorry Chewie I do not understand."
"Graaaaahh!" he said, becoming more and more frustrated.
Han signed. This was going to be one long spaceflight.
"Here you go Chewie!" Han reached into his pack and pulled out some food. It was dense and sticky. Chewbacca took it excitedly and tried to eat it. It was very difficult. This was intentional. His mouth would be occupied for the duration of the trip.
The Falcon landed on a secret planet where beings with embarrassing disorders always go for help. The two stepped off into a sea of madness. All around them everyone had some disorder or disability. Some of them were invisible to the naked eye. Some of them were behavioural. Some of them were physical. Whatever they were, it was the weirdest band of misfits in the galaxy. Here Chewbacca would begin his long and perilous quest for a clear voice.
