Nacho Sierra studies psychology at the Universidad Complutense in Madrid, and although the subject of his studies has always been animal behaviour, he is taking us by surprise with this amusing book about the male of the human species.

He had already established his credentials in the world of humour with books such as Cómo Tener un Perro y no Perder la Cabeza or in the ironic and transgressive Mono Enmascarado), as well as with his audacious forays into the world of monologues.

Those who know his understand that Nacho uses humour as one of his main virtues and character traits. His ironic, black and even sarcastic sense of humour springs from her critical and profound views on a life “full of experiences”.
