Potter Puppet Pals is a Harry Potter puppet parody series created by Neil Cicierega, and The Mysterious Ticking Noise became its breakout episode after appearing online in 2007. In the sketch the puppets investigate a rhythmic ticking and turn the names Snape, Dumbledore, Ron, Hermione and Harry into a looping chant that stuck in viewers' memories. The video spread widely in the early YouTube era and is still quoted by fans, which is why even a fraction of a second of that ticking now works as instant shorthand for the whole scene.
