Ghostbusters began as a 1984 comedy film about a team of paranormal investigators in New York, and its music and imagery soon became shorthand for anything ghostly, funny or slightly spooky. Over the following decades the franchise returned in sequels, cartoons and reboots, keeping the theme familiar to new audiences. Online, short clips like this one are reused every Halloween and in reaction videos because seven seconds is enough to set the mood instantly without interrupting the joke, edit or reveal that follows.
