A high school student managed to "rickroll" his physics teacher, cleverly inserting the lyrics of Rick Astley's '80s hit "Never Gonna Give You Up" and lining the words up perfectly.
Even more impressive, the essay on scientist Niels Bohr actually makes perfect sense. It's hard enough to write a physics essay, but we don't even want to think about how much time it took student Sairam Gudiseva to "rickroll" his teacher.
Hopefully he got an A for creativity.
Yahoo! News explains the origin behind the term "rickrolling":
Going back years, rickrolling is a term for getting victims to watch Rick Astley when they least expect to. Sometimes, during a boring video, the merry prankster will cut to Astley a few minutes in and let his melodic rock crash over you like the rushing tides of the Pacific Ocean, so gentle, so free.
You may have thought rickrolling had jumped the shark, but no. You just can't keep a good prank down. It is worth noting that Gudiseva isn't the first student to pull the essay prank. In 2010, using a never ending stream of Astley lyrics in a computer essay, a student pulled a similar stunt.
