With a BRILLIANT trick, this math teacher will make you cry laughing !

The awesome professor you see in the video is Matthew Weathers, he teaches maths and computer science at Biola University in California, and every year, on the first of April he usually organizes a prank to his students. What you see is his lecture on April 1st, 2015, which combines creativity, video manipulation and irony to give to the students (and us) a hilarious moment. This is the passion with which a teacher has to deal with his work!
