'Young Sheldon' episodes: 'A Computer, a Plastic Pony, and a Case of Beer'

The episode before "A Sneeze, Detention, and Sissy Spacek" was "A Computer, a Plastic Pony, and a Case of Beer," which aired on CBS on Jan. 18. It showed Sheldon asking Mary to buy him a computer (Tandy 1000 SL). George told them that they simply can't afford to get one. However, Mary eventually revealed that they have some money saved up in their secret fund. George and Mary argued about it, prompting the latter to take Missy and Sheldon to live with their Meemaw for a short period of time.

Mary still bought Sheldon the computer, despite her argument with George. Unfortunately, Sheldon was dissatisfied with the computer because he found its psychotherapy program quite useless. Thankfully, Georgie advised him to just pretend to apologise to Mary, who heard him complaining about the new computer. Despite Sheldon's dissatisfaction with the computer, his family still found lots of ways to use it. Richie Keen directed this episode. Tara Hernandez, Chuck Lorre and Steven Molaro wrote its teleplay, while Molaro and Lorre wrote the story.
