>>88208628Jimmy has actually been able to manipulate time freezing it at times and even turning back time in others, such as when he was having a party with a girl he was lusting after he simply slowed time to alter time in order to solve the problem, showing that his blindness never reaches past the point where it will hinder him.
>>88208650There was an episode where he actually managed to "Dumb down" him self with a device he made altering his brain waves, changing his personality and his way of thinking, the very same device he used also managed to reverse such effects keepign all memories, also an episode that shows that memories and personality trains could be swapped and put into people such as when He and Cindy swapped bodies.
This showing he has been able to alter his own mind with his machines, altering one to be illogical and random would not be far from these already established mind altering devices. Also keep in mind he managed to input information through food such as those book gummies he gave to his friend in one episode. Jimmy knows the brain.
