Back in early 2007 a video was uploaded to YouTube that has since become wildly popular. It was made by a group of people who call themselves Potter Puppet Pals and they have made many videos, all based on the characters we love so much.
Some of the Potter Puppet Pals videos are better than others, but there is one that stands out above all others, and that video is the one seen below. It is called The Mysterious Ticking Noise and it is undeniably catchy. I've listened to it multiple times and love it each time. My kids and I will often start singing, and the best part about this song is that one person starts, then another person jumps in, and then another, for however many people are in the room.
Even if you've heard it before, I invite you to watch The Mysterious Ticking Noise again. It is well worth watching over and over. Don't be surprised if sometime in the future you catch yourself starting to sing, "Snape, Snape, Severus Snape..."
