The Bloopers From All 3 Seasons of Stranger Things Will Serve You Scoops of Laughter

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 blooper reels from all three seasons. And they're 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 clips ahead, then read up on all the juicy details we have about season four!
