Lyrics
Bone to be wild! Bone to be wild!

Bone to be wild! Bone to be wild!

Bone! Bone!

Bone! Bone!

Bone! Bone!

Bone! Bone!

Bone! Bone! Bone!

Bone!

It's nonsense to become macho just to attract women.

Soul King is mysterious.

He's nothing but bones!

Afro on the skull! Girls love the contrast

If you wanna make out with her

Got milk! Got milk!

You need calcium more than protein

Trivia

 * The song's name is a parody of the song Born to Be Wild by the band Steppenwolf.
