-Lewis Carroll, "Alice in (DC) Wonderland"
Tweedledum and Tweedledee
Agreed to have a battle;
For Tweedledum said Tweedledee
Had spoiled his nice new rattle.
Just then flew down a monstrous crow*,
As black as a tar-barrel;
Which frightened both the heroes so,
They quite forgot their quarrel
*monstrous crow... aka - "Trump tariff threat"
