George Jr.: Woah, someone woke up on the wrong side of the bed. And you had both sides to choose from.
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.
