I’ve gotten papers with little comments or song lyrics embedded in the prose. I assumed they were little tests to see if I was actually reading the paper. I note it as a technique of surveillance or accountability.
This is a whole extra level of thoughtfulness. Rick-rolling without really altering the content of your paper.
I wonder if this was really a paper for this class or was it made as a gag?
