Unexpected Rickroll
For as long as we can remember, the Rickroll has been a popular prank. Rickrolling is the act of tricking your friends into watching a video by clicking a hyperlink. When the YouTube page loads, the friend or online stranger will be directed to a music video for Rick Astley’s 1987 song “Never Gonna Give You Up.”

This troll took the feeling to a whole new level, bringing this funny occurrence out of the virtual realm and into the real world. Every line of this physics paper begins with the lines from the song, so consider yourself Rickrolled if you read the first word of each line in vertical order.
