The world’s worst poem?

“William McGonagall is under the direst threat today in his apparently unassailable position as author of the world’s worst poem.

The 19th century Scots bard’s notorious lament for The Tay Bridge Disaster:

And the cry rang out all o’er the town, Good Heavens! the Tay Bridge is blown down

has been challenged in favour of a single appalling last line by a more exotic British versifier, Theophile Jules-Henri Marzials: “Drop / Dead. / Plop, flop. / Plop”.

The poem is titled A Tragedy. The opening lines: “Death!/ Plop. / The barges down in the river flop. / Flop, / plop,” suggest that the author is brooding about suicide.

The 1873 collection of verse in which it was published, The Gallery of Pigeons, was once highly praised. But – in picking Marzials as one of the new entries for its website today- the Oxford Dictionary of National Biography says the poem is now claimed as the worst ever written. It quotes the last line as an example.”
