Stranger Things might be a sci-fi thriller filled with jump scares and terrifying moments, but behind the scenes is a different story. In celebration of Stranger Things Day — which takes place on Nov. 6, aka the day Will Byers (Noah Schnapp) first goes missing — the cast and crew graced us with a season three blooper reel. And it's filled with everything you could hope for: singing, dancing, adorable moments, and a lot of on-set mishaps. The stars even have a hard time saying some of their lines without cracking up, especially David Harbour, who thinks the word "grandma" is hilarious. Watch the cast members goof around in the clip above, then read up on all the juicy details we have about season four!
