From Forbes:
Every Who down in Whoville liked Christmas a lot....Continued
But the Grinch, who lived just north of Whoville, DID NOT.
He stood and he hated the Whos and their noise
He hated the shrieks of the Who girls and boys
For fifty-three years he’d put up with it now—
He had to stop Christmas from coming, somehow.
He asked and he questioned the whole thing’s legality
Then his eyes brightened: he screamed “externality!”
He reached for his textbooks; he knew what to do
He’d fight them with ideas from A.C. Pigou
