ZURICH, Switzerland – A popular professor at a Zurich business school has been suspended after accidentally broadcasting porn from an adult tube site during a lecture.

The unnamed professor, described by the school as a veteran educator, apparently had been using a laptop computer to project class materials onto a wall in a lecture hall and neglected to disconnect the laptop from the projector before surfing over to Pornhub during a break in class.

According to students who reported the slip to administrators, the professor’s unintentional display also revealed he had been searching for explicit images of female amputees.

“I am shocked,” school director René Portenier told the Swiss edition of daily newspaper 20 Minutes. “After the class, the teacher immediately came to me and told me he had watched porn on a school computer. He was very embarrassed and could not tell me why he did it.”

Rolf Butz, the school’s chairman, called the professor’s 40-year career exemplary, but said the porn misstep was “unacceptable.”

The suspension may not be permanent, Portenier told 20 Minutes.

“In three weeks, we will make an assessment with students and an expert on whether to take action or not,” he said. “I realize very well that some students are disturbed after what happened.”
