Continuity mistake: When Sheldon and Missy are sitting at the table, Missy puts a paper in the basket in front of her. A couple of shots later when she says "sounds right" the paper has disappeared. In the next shot it reappears, in a different position than it was before. (00:06:20)
Continuity mistake: At the start, the cards in Sheldon's hands keep changing between shots. (00:00:40)
Continuity mistake: In this episode, the voice over version of Sheldon states that he never got his drivers licence. However, in series 12 of The Big Bang Theory, he tells Amy that he got his drivers licence 2 years ago. (00:11:40)
Answer: It is shown numerous time in The Big Bang Theory and Young Sheldon that Georgir Jr is not the smartest kid going. They simply tell him Sheldon is getting a hair cut as it is believable. It's also shown that Sheldon has had the same style hair cut since he was 5. Since he is 9 in Young Sheldon, he's had the same style for over 4 years already. Easy to overlook that he hadn't actually had it cut after that long.
