18. Green bean casserole
People talk about how much they love this cauldron of beans, fried onions, and Campbell's Cream of Mushroom, but then they only take a spoonful. There's a reason you only see this once a year.
17. Cranberry sauce
It's always there, sitting on the table, usually still shaped like a can, ribbed perimeter and all. If it's not there, somebody will freak out. That same person won't touch it.
16. Candied yams
People always confuse these for sweet potatoes, and we're not really sure what the difference is, except for the fact that these are usually round, don't have marshmallows, and are kind of gross if you didn't grow up eating them.
