As the well-attested case of Sweeny shows
Mad kings gain the gift of flight, sleep rough,
Perch in trees, speak the language of birds.
Mad princes hover a few inches above the ground
And can follow a conversation among sparrows
A mad archduke gains a modicum of grace
And the grass does not bend beneath his feet.
When a commoner is found doing loops
Five hundred feet up the government
Immediately raises him to the peerage.
