A Swiss professor was sacked after he accidentally showed an X-rated porn film on the class projector.
The professor had just finished a lecture at a business school in Zurich when he visited an adult video site Pornhub.
According to a Swiss newspaper 20 Minutes, he was caught after he forgot to unplug the cable linked to his work computer to the overhead projector, Metro.co.uk reported.
Rene Portenier, the director of the school said that he was shocked with such behavior after the professor came to him and admitted that he had watched porn on the computer.
