This is a Mexican song, allegedly about two brothers, both firemen in La Fiuerro del Servicio de Mechico Nationale (the Mexican National Fire Service); twins they were, and no one could tell them apart – sometimes they even confused themselves as to whom was whom.
One brother, we shall call him José, was the oldest by a matter of minutes, the other… Joseby was the younger by a similar amount of minutes.
I give you ‘Chihuahua!’
