Have a bed jumping competition. Document your successes and failures. Take a day trip to a town you've never been. Discover all the little coffee shops and quirks. Wear a cape around the house. If a delivery person comes, thank him for his fastidious service to your cause. Buy a sex swing. Display it proudly in your living room. Get a giant birdcage; keep little notes in it. Paint one of your walls chalkboard. Write poems, naughty humor, or to do lists. Get a bunch of kids crafts and make rock pets, pipe cleaner animals, and macaroni drawings. Wear bright mismatched socks. Practice your cartwheels. Buy bubble guns and attack people in the street. (make sure they look like bubble guns and not real guns though!) Go commando Make a working palanquin. Take turns riding in it while popping grapes in your mouth ceremoniously. Rediscover an old video game like Lemmings. Relive your life at the time. Buy a cheap instrument at a thrift store. Pretend to be able to play it.
