Georgie will have mathematics test and his father asks Sheldon to teach him; otherwise, he will not be allowed to play football anymore. In return, George will give a new train for him. Sheldon considers his brother a lost case, but Georgie surprisingly has a B+ in the test. Soon Sheldon learns that Georgie cheated the test and Georgie teaches him how to cheat.
"Spock, Kirk, and Testicular Hernia" is another funny and sarcastic episode of Sheldon, where he learns how to cheat with his older brother. Further, he also learns that there are people, like Georgie, that needs to cheat. Sheldon forging a letter from his mother to the school teacher to skip the physical education classes is hilarious. In the end, the family is happy, Georgie can play football and Sheldon has a new train. My vote is eight.
Title (Brazil): "Spock, Kirk, and Testicular Hernia"
