For small kids in particular, it doesn't take much to turn an ordinary living room into a makeshift playground. A few sheets draped strategically around armchairs and couches can quickly morph furniture into a fabulous indoor fort perfect for your whole family.
Split up into teams and compete by seeing who can build the best castle out of blocks or who can fashion the most realist animals from modeling clay. Everyone is sure to get a good laugh out of playing dress-up with your old clothes from the '80s, although some of them might look frighteningly similar to current fashion trends. Your kids will certainly appreciate the chance to catch a glimpse of the rarely seen extra-silly sides of their usually serious parents.
