Ok here is the scenario we all know one situation that makes young Sheldon crazier than anything else, going to the doctor. I mean anytime he gets sick or is in the presence of germs he goes nuts right. OK so Sheldon gets sick and has to go to the hospital, he is the waiting room to see a doctor. He has basically made all the doctors and nurses crazy. Then and here is the idea when the doctor walks in to see young Sheldon, its Neil Patrick Harris in a doctors outfit playing you know who LOL. Can you imagine the teasers "Only one man can treat this 9 year old."
