Sex education recently took on a whole new meaning in the Netherlands.

A professor at Wageningen University (which sounds like a name made up by a Nickelodeon writer) accidentally left a projector on while he de-stressed with a little porn in his classroom. Whoops.

The professor, who was visiting from Belgium’s Ghent University, was scouring an X-rated website on a computer that he didn’t realize was hooked up to a projector, which was on. Kind of makes all those times you checked to make sure your parents weren’t coming upstairs while you searched “Megan Fox Naked” seem pretty tame, huh?

It turns out the prof had just used the computer to deliver a lecture to an Advanced Food Chemistry class, which we would imagine might have made him yearn to unwind and watch people with a carnal kind of chemistry.

The classroom was empty, but students who had watched the lecture online managed to see what happened, which just goes to show you that it does not pay to leave class early. Someone took a screenshot of the fleshy activities and told school officials, who, for some reason, asked the professor to leave.

We don’t blame the guy. This did happen in the Netherlands after all, a country famed for its red light district. You’d think when word broke out a professor was watching porn, they would have offered him a joint and a Kleenex.

Ironically, students said he was “an excellent teacher.” Well, of course he was. He shows porn on a projector. The man thinks big.
