"TIL that in the 1950s, a psychiatrist had three paranoid schizophrenic patients who each believed they were Jesus Christ. He put them in a room together to see if their beliefs would change after confronting each other. They did not, in fact, change their beliefs but each individually came to the conclusion that the other two men were insane. They made a movie about it, called Three Christs."
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.
