Have one of those group house shows with cameras recording everything. Anything the residents need to do must use an item from "As Seen on TV". Cooking use the Express griddle or the Ronco oven. Cleaning, use the Swivel Sweeper or the Shark vacuum. If they need to hang something on the wall use Herculese Hooks.
All products and tools must be from the As Seen on TV website.
Since some items make using a microwave easier, it would be allowed. Same thing for a refridgerator.
