A professor at the University of Toronto accidentally displayed hardcore pornography on the lecture hall projector screen while teaching to a packed class of about 500 students.
The students were expecting an introductory psychology but instead got a lesson in human anatomy and sexual behavior.
While the spectacle lasted only a few seconds, several shocked students walked out, while others found it hilarious.
One student managed to capture the incident on Snapchat, which has been shared over and over.
The school won't comment on the incident but has offered services to any student who was disturbed.
