"Si Acabo (La Malanga)" (Bobby Hutcherson, Montara)

The most well-known quote from Malcolm Lowry's Under The Volcano translates oddly online.

"¿LE GUSTA ESTE JARDIN, QUE ES SUYO? ¡EVITE QUE SUS HIJOS LO DESTRUYAN!"

(Rough simple translation: "Do you like this garden that is yours? Be careful that your children don't destroy it!")

(The soft voice of http://ets.freetranslation.com/: He likes this garden, that is its? Avoid that its children destroy it!)

But there are worse translations.
