A rotisserre, by far the best as seen on TV thing made.
Owned a foreman grill for a while, But I grill year round outside (regardless if it is cold or not) so gave the thing to friend who's nipples stick out when it drops below 60.
The upside down hanging tomato growing things are cool. My kids love tomatoes but my danes love eating compost so a garden is a pain. it is a win win.
