The average human head measures about 22 inches in circumference and weighs about 12 pounds...but Doctor Shoal sports a gigantic 48 incher,
so you just KNOW that thing's gotta weigh a LOT!
As a result carrying around such an enormous head, the Doctah has pretty much written the book on developing one's neck muscles...and it is available for purchase for only 25 cents (in coin)...so get yours today and Doctor Shoal will throw in a complimentary dance lesson absolutely free!
