Chorus:
Mable Ka-dabel,
fee-fi-fo fable
Okin-kabokin was her name!

She had two hairs on her head,
One was black and the other was red, oh:

(chorus)

She had two eyes in her face
One wasn't there, so the other took its place, oh:

(chorus)

She had two pimples on her nose
One wore socks, and the other panty hose, oh:

(Chorus)

She had two teeth in her mouth
One pointed north and the other pointed south, oh:

(chorus)

(continue with other body parts as long as you can, coming up with outrageous mismatched pairs)

(But I also liked to sing the "nice" songs too -- I really did!)
