The popcorn maker, cause it is just easier to buy microwaveable popcorn. The donut maker, it makes tiny donuts though. I have a huge section in my linen press that is dedicated to stuff I've never used, but they've been wedding presents etc. I went to get rid of stuff once and my mum said "You'll have parties and stuff one day and you might need some of that" I think I have used 3 or 4 things since then LOL. I even have a box of odds and ends cutlery. I have my fair share of tupperware gadgets as well.
