A nice clean tandem makes decent wall art. I know several people who hang their bikes in their living space.
Tandems are forbidden on the MAX trains here. Bikes hang from a hook by their front wheels. I have taken our (fendered) tandem and stood it straight up on its back wheel with the front turned 90*. I think all rear fenders are cut higher than front fenders for just this reason. The security enforcer started to say something then just shook his head and walked away.
