Yakko: Everybody knows about the ankle bone connected to the
       Other bones you have inside your leg.
Wakko: And everybody knows it's true,
       Without the bones inside of you,
Dot: Your body would become a scrambled egg.

Yakko: So the toe bone's connected to the foot bone,
Wakko: And the foot bone's connected to the ankle bone,
Dot: And slide is connected to the trombone.

Yakko: The structure of the human body's
       Something quite unique
       And I'd imagine all the bones and joints
       Connected to each other
       In a complex distribution
       Formed by years of evolution
       That there still is some confusion
       As to how it came to be.

Wakko: The foot and toes and ankle
       Help us walk; we should be thankful
       They're connected to the lower leg
       Or else we'd all fall down
       Right, here's the tibia, the shin bone
       And the fibula is ingrown
       To the back of the patella
       Which is also called the knee.

YW+D: Knee knee knee knee knee knee knee,
       Knee knee knee knee knee knee knee.
       Knee knee knee knee knee knee knee,
       Knee knee knee knee knee.

Dot: Here we classify bone as the
       Femur or the thigh bone
       It's connected to the pelvis
       And the lower lumbar region
       Up the sacrum to the vertebrae
       And doctors all prefer to say
       The sternum or the thorax
       When they're talkin' 'bout your ribs.

Yakko: The finger bones are numerous
Wakko: The upper arm's the humerus
Dot: The forearm's got two pieces
       Called the radius and ulna
Yakko: Then the scapula and clavicle
Wakko: The maxilla and mandible
Dot: The nasal and the frontal bone
       And cranium on top. Mwah!

Yakko: The skeleton is really great
Wakko: It helps your body stand up straight
YW+D: Without it all your brains and guts
       Would fall out on the floor!
