Bullfighting book No puede ser y además es imposible

It can not be and therefore it is impossible, is a series of stories and anecdotes gathered in a book by journalist Ruben Amon.
It is said that this famous phrase was pronounced by the bullfighter 'Guerrita' when some of his supporters told him that an illustrious predecessor, a Cordoba bullfighter, Manuel Rodriguez Manolete, was able to give a bull six and a half veronicas with his bullfighting cape.

The phrase, which became a proverb, is in force since then, and is applicable to a thousand of situations of the daily life.
