Where No Sheldon Has Gone Before

"Where No Sheldon Has Gone Before" was a short fan novella based on Star Trek: The Original Series, and based on a fan written story (written by Sheldon) depicting, when Spock takes Sheldon (who was then 10-years-old at the time he wrote it) from his homes on the Backwoods of East Texas to the 23rd Century to help the Crew of the Enterprise save the Galaxy. Sheldon also converts the first 5th of the Novella into the First Act of a play as part of his acting lessons from Penny. However, when he portrayed his mother, Mary and tried to act emotional for the scene where 10-year-old Sheldon left for the 23rd Century, it caused Sheldon to actually emotionally break down into sobs.
