Picture this. It’s 9:40 a.m. and you’re writing one of your first-ever university tests when the ominous beats of Coolio’s Gangster’s Paradise suddenly fill the room. The professor looks confused. “What’s going on?,” he says. A student stands up on the desk beside you and starts rapping. That’s just the beginning of what happened in a University of Toronto engineering class this week. Skule Nite, which describes itself as “The World Famous Engineering Musical Comedy Revue,” was behind the stunt that has nearly two million views on YouTube already. Oh those clever engineers.
