It’s the Potter Puppet Pals, in “The Mysterious Ticking Noise.”
Since this is one of the most-viewed videos on YouTube, the odds are that one out of every five of you has seen this. That’s an amazing statistic for something that doesn’t involve kittens in funny hats, scatological humor, pornography, or someone getting hit in the groin with a football. More amazing is that it’s clever and catchy… it will take days to get the “Snape” song out of your head.
