My math teacher was inspired by Westerville South's math music videos, and decided to make it an academic class project. Him, a buddy, and I spent around 20 hours just lining up the music and video, putting in transitions, and piecing it all together. The times where the vocals don't match the lips are the fault of the transitions, but we were tired of working on it lol. It was definitely fun. btw, the teacher's the guy in the fedora.
Same year, different song:
