An electric individual mini pie maker that my husband just had to have. It came with little rings to cut the right size of crust and then the pies bake for 20 minutes. What it didn't come with was a taste for canned pie filling, so when hubby wants to use his gadget, I have to chop, peel and cook pie fillings for him.
I use all the weird stuff though...garlic press, herb mincer, egg slicer, citrus zester, pastry wheel, cookie scoops, mortar and pestle, baker's blade, etc...
Oh, the other useless gadget are spatulas that break off in the mixing bowl. I've killed four spatulas this year, one of them being the Kitchen Aid one specially shaped to fit the mixer bowl.
