Full House is known for providing tons of warm and fuzzy moments, and none of the many feelings that you most often have while watching the show would make you think it has any even minorly scary scenes. But then again, it doesn't make sense to have a show that follows a few young kids and not include some storylines about those kids getting scared, so there are in fact many Full House quotes that are spooky AF. Kids get scared a lot, so it only makes sense that the Tanner kids would have a few freaked-out moments.
You probably don't think about Full House as a good show to get yourself pumped up for Halloween, but once you revisit some of the episodes about Michelle (Mary-Kate and Ashley Olsen), Stephanie (Jodie Sweetin), and DJ (Candace Cameron Bure) getting spooked out by certain mysterious happenings or downright terrifying ghost stories, you'll find that Full House has a lot of great Halloween material.
Of all the episodes that might give you a fright, the first episode of Season 7, called "It Was a Dark and Stormy Night", is by far the scariest of the whole series. But you'd be surprised by how many other episodes had a few spooky quotes included amongst the warm and fuzzy ones.
