Weird Al says: WTF!?
Human fingers do not contain any muscles other than the small muscles attached to each hair follicle, which contract to make the hairs stand on end, causing goose bumps. The muscles that move the finger joints are in the palm and forearm. The long tendons that deliver motion from the forearm muscles may be observed to move underneath the skin at the wrist and on the back of the hand.
This has been a moment of ... WTF?!
