I like the idea of making it look like someone robbed it. Do this in exact order.
1. Take some stuff that isn't quite important, but normal in your life, and hide them IE; Silverware, a few plates, some pens from a workspace, some CDs.
2. Hide the Wii and this stuff in a good place.
3. Go outside and through a rock into the window to make it look like someone got in. Don't worry, your parents will pay for it.
4. ????
5. Profit.
