Even the Grinch wouldn't be this mean.
A sourpuss teacher in Rockland County ruined Christmas for a class full of second-graders this week, when she told them that there is no Santa Claus during a lesson about the North Pole.
The evil educator even told the youngsters — mostly 7- and 8-year-olds — that the presents under their trees were put out by their parents, and not St. Nick.
The stunning Scrooge-like behavior has caused a blizzard of outrage at the quiet George W. Miller Elementary School in Nanuet, where angry parents would like to see the teacher roasted like a chestnut over an open fire.
"If that happened to my daughter in her second-grade class . . . I'd be very upset," said, Sean Flanagan, 48, whose child was in second grade at the school last year.
"If her brothers told her [there was no Santa], they would be punished. So I can't imagine what should happen to the teacher."
A nanny picking up a child at the school yesterday told The Post that anyone who tells kids that Santa doesn't exist should get coal in their stocking.
"It's outrageous that a teacher would strip a child of their innocence and try and demystify something," said Margaret Fernandez, 59.
A grandmother of a kindergartner said, "I think this is awful.
"If it happened to my granddaughter, I'd tell her her teacher made a mistake, and there is a Santa," she added.
The unidentified teacher reportedly made her anti-Santa comments Tuesday during a geography lesson, when students told her that they knew where the North Pole was because that's where Santa lives.
