If you're bored with rote holiday decorations, consider adorning your living room with a pineapple instead of a Christmas tree. For some reason, people on Instagram have decided to replace their trees with festive fruits this year. The trend started on Pinterest, probably because people realized pineapples look pretty cool with sunglasses. They're basically just like normal tropical fruits, only with more attitude. But it's really gotten out of control from there, as all of the pictures of pineapples draped with Christmas lights demonstrate.
