"TIL of The Great Hanoi Rat Massacre of 1902. The French wanted rats exterminated from the sewer system. They set a bounty for each dead rat tail. Thousands of tails were submitted per day but the rat problem only grew worse. They found the hunters were breeding, not hunting, rats for their tails."
Between the crosses, row on row
That mark our place; and in the sky
The larks, still bravely singing, fly
Scarce heard amid the guns below
We are the dead. Short days ago
We lived, felt dawn, saw sunset glow,
Loved and were loved, and now we lie
In Flanders fields.
