A professor has been sacked after he accidentally beamed porn through a lecture room projector for all his students to see.
The "popular" veteran teacher was in the middle of a lecture at a Zurich business school when he started watching a video on the Pornhub website.
He apparently didn't realise his laptop was still plugged into the projector, meaning the images were broadcast onto a huge whiteboard.
The students also saw that he had been searching for images of naked amputee women, Swiss news site 20 Minutes, reports.
Following the incident, officials at the school decided he had to be laid off.
