When I was little my youngest brother who was like 5 told my mom he saw double. Mom freaked out he had a MRI done, came back negative then told my mom afterward hr could make himself to it with his finger to his nose. Good stuff
I've had a few MRI's and a couple CT Scans. Didn't mind them at all. Although the stuff they inject you with for the CT will warm you up and light your balls on fire. That's pretty weird.
