Humpty Dumpty, the egg that fell from the wall, is well known by all of the English speakers. It appears in the title of the film about Watergate affair, called in Spain TODOS LOS HOMBRES DEL PRESIDENTE, alluding to the impossibility of mending an egg that has fallen from the wall.
Humpty-Dumpty sat on a wall,
Humpty-Dumpty had a great fall.
All the king's horses and all the king's men
couldn't put Humpty together again.
