Itchy Butt Syndrome

I saw a commercial for something the other day that made me laugh out loud. It was a pill for Restless Leg Syndrome. You've got to be kidding me. Restless Leg Syndrome? Is that actually a thing? Sometimes I have a hard time keeping my hands still. Does that mean I have Restless Hand Syndrome? Oh, and my butt itches. Do I have Itchy Butt Syndrome?!?
