Sometimes, the internet gives birth to the most offbeat of experiences. People use all manner of medium to show off their skills, whether it’s in cosplay, animation, or even macrame.

In this case, Youtuber “neetsama hataraku” uploaded a video displaying the musical talents of a particularly gifted individual. This person doesn’t use a normal instrument, though. Instead, he uses a combination of concentration, strong fingers, and a good-old-fashioned ruler to perform a rendition of the first Attack on Titan opening theme. The result is a combination of the impressive and the amusing, as the subject’s able to nail the rendition perfectly, even though a perfectly played tune on a ruler sounds like something out of a Looney Tunes sight gag.
