It may be a week later, but this April Fools’ prank is worth the watch. When a students’ phone rings in this professor’s class, his ‘punishment’ is that you have to answer the call and talk to the person on the line in front of the class. So, this student and her friend scheme up a brilliant (at the time mortifying) plan to use this professor’s rule against him to the point of complete humiliation. No worries, though, they eventually tell him it’s a joke and his reaction is even better!
