Poems in which the title is, in fact, the opening line.
And what appears to be the first line is really the second.
Failing to spot this device may result in the reader,
Unnerved and confused, giving up halfway through,
And either turning to another poem with a decent title
That invites him in, or (and this is more likely),
Throwing the book across the room and storming out
Into the voluptuous night* vowing never to return.
