Look, if you're gonna watch porn in class, at least be discreet about it. That may seem like obvious advice, but some people apparently need a little reminder.

A visiting professor at Wageningen University in the Netherlands was caught logging onto PornHub in a campus classroom. The university didn't have to search his laptop to discover he was watching dirty material: it was actually pretty obvious, because he forgot to unhook his laptop from the projector. On the projector? A really close up video of some naked ladyparts.

Worse, the class was being taped for online viewing, which means his indiscretion was forever recorded for everyone to see. A Redditor posted a screenshot to r/WTF (it's pretty NSFW), and a Dutch news source confirmed the story. He's not welcome back to the university, for obvious reasons.

Hey, free advertising for PornHub, we suppose.

Update:

Of course some enterprising Redditor figured out what (VERY NSFW) video the prof was watching. It's called "TIED AMATEUR GIRLFRIEND HOMEMADE BLOWJOB WITH FACIAL CUMSHOT," in case you were wondering. It's almost like the creator just typed every porn tag he could think of into the title, but whatever works.

Update 2:

PornHub has offered a free membership to the professor, so maybe this was kind of worth it?
