All these people have stupid ideas, save for jousting which is a bit impractical together into.
I suggest whitewater kayaking. Rafting is good too, but requires a team. Look around for a whiewater stadium which might be a bit hard to find, but there should be some around somewhere, learn the basics and most importantly how to roll back up, once you can roll, you can try anything. Before you know it you'll be surfing and cartwheeling with the best.
Ice hockey is also acceptable.
