I'm sure it exists outside of this poem, and with different nationalities slotted in where they belong, but I quote unaltered. Easier to just c+p, really.
In the Belgian Army, the feud
Between the Flemings and Walloons grew vicious,
So out of hand the army could barely function.
Finally one commander assembled his men
In one great room, to deal with things directly.
They stood before him at attention. "All Flemings,"
He ordered, "to the left wall." Half the men
Clustered to the left. "Now all Walloons," he ordered,
"Move to the right." An equal number crowded
Against the right wall. Only one man remained
At attention in the middle: "What are you, soldier?"
Saluting, the man said, "Sir, I am a Belgian."
"Why, that's astonishing, Corporal–what's your name?"
Saluting again, "Rabinowitz," he answered
