I once wrote the football results in the middle of a literature paper to see if the teacher was really reading it. This guy included Rick Astley's Never Gonna Give You Up in acrostic form. Updated.
The computer science student, Reddit user Mayniac182, spent five hours formatting his paper into the acrostic Rickroll you can see in the video and the image below.
Update: Mayniac182 just told me that his class is getting the papers back tomorrow. If the professor returns the paper without marking the rickroll, he's thinking about playing the video I made in the class projector. Check back tomorrow for the final outcome of the story. [Buzzfeed via Geekosystem]
