A teacher ruined Christmas for a class full of second-graders when she told them that there is no Santa Claus during a lesson about the North Pole at their Rockland County, N.Y., school.

The 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 behavior 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," according to 48-year-old Sean Flanagan, 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 said that anyone who tells kids that Santa does not 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," 59-year-old Margaret Fernandez said.

A grandmother of a kindergartener added, "I think this is awful. If it happened to my granddaughter, I'd tell her [that] her teacher made a mistake, and there is a Santa."

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 is where Santa lives.

School officials would not discuss the Christmas incident or say if the teacher would face any discipline.

District Superintendent Mark McNeill released a brief statement, saying only, "This matter is being addressed internally."
