amazing things you can do with a bike

Someone I know once moved a piano by bike. And here's a guy who plays a piano bike. And a guy in Ottawa, Canada, moving the contents of his home by bike. Here's another bike move in Austin, Texas. A group of folks in Portland, Oregon, moves puppet theater props and puppets by bike. I've got a ways to go before I can equal these. What's the most creative thing you've done with your bike?
