Ep 20. A Baby Tooth and the Egyptian God of Knowledge

Young Sheldon season 3 episode 20, titled A Baby Tooth and the Egyptian God of Knowledge, follows Sheldon as he comes to terms with losing his last baby tooth. For Sheldon, losing his last baby tooth is a major milestone and he wants to make sure that the tooth is treated with the respect that it deserves. The episode is set against the backdrop of an upcoming Egyptian exhibit at the local museum, which has piqued Sheldon's interest in the history and mythology of ancient Egypt.

As Sheldon prepares to lose his last baby tooth, he becomes increasingly obsessed with the idea of preserving it. He spends hours researching the best ways to keep a baby tooth safe and enlists the help of his siblings to find the perfect container. In a moment of inspiration, Sheldon decides to create a replica of the Egyptian god of knowledge, Thoth, out of clay and use it as a tooth holder. He believes that Thoth, who was known as the god of writing, magic, and wisdom, would be the perfect protector for his last baby tooth.

While Sheldon is immersed in his tooth preservation project, the rest of the family is busy preparing for the upcoming Egyptian exhibit. Meemaw is helping to coordinate the event and inviting her friends from the museum to attend, and Mary is worried about the cost of admission. George Sr. is less interested in the exhibit, but he is happy to support his family's interests.

As the day of the exhibit approaches, Sheldon becomes increasingly agitated about his lost tooth. He worries that it will be lost forever and that he will never be able to share it with his future child. Meemaw tries to reassure him that losing baby teeth is a normal part of growing up, but Sheldon is determined to hold onto this last tooth.

At the exhibit, Sheldon is fascinated by the ancient artifacts on display. He spends hours examining the intricate carvings on the sarcophagi and the hieroglyphs on the walls. He is particularly interested in the story of Osiris, the god of the afterlife, who was killed by his brother and then resurrected by his wife, Isis. Sheldon sees parallels between the story of Osiris and his own struggle with losing his last baby tooth.

In the end, Sheldon realizes that he cannot hold onto his baby tooth forever. He accepts that it is a natural part of growing up and decides to let it go. He places the tooth in his Thoth replica, which he proudly shows to his family. Meemaw and his siblings are impressed by the quality of his work and Sheldon feels a sense of satisfaction knowing that his first attempt at clay sculpting was a success.

Overall, Young Sheldon season 3 episode 20 is a heartwarming and engaging episode that explores the themes of growing up, letting go, and appreciating the wonders of the past. It is a touching reminder of the importance of family, tradition, and history, and it is sure to leave viewers feeling both entertained and enlightened.
