"¿Conoces al boticario del pueblo al lado de Candelario?
En vez de cabeza,
Tiene una cereza.
No ve ni torta, claro."

(Do you know the apothecary
from that village next to Candelario?
Instead of a head,
He's got a cherry.
He's as blind as a bat, of course)

Laurence Saum wrote something like this years and years ago and for some strange reason his daughter remembered it today.
