Garlic, Onions, and Shallots
With the exception of spring onions and scallions, alliums shouldn’t be stored in the fridge. These bulbs benefit from being kept in a cool, dry, dark place. And make sure to avoid wrapping them in plastic bags. Your shallots, onions, and garlic want to breathe! And breathing in a plastic bag isn’t the easiest thing to do.
Hard Squashes
You should store summer squash (like zucchini) in the fridge, but thick-skinned squash like acorn, butternut, or kabocha should stay at room temperature. This is partially to preserve their texture, but it’s mostly because squash tend to take up a lot of real estate in the drawers and on the shelves of your fridge. It’s crowded enough as it is in there, so keep those hard squash out on the counter and save that space for something else.

Potatoes and Sweet Potatoes
Similar to the alliums we were talking about earlier, you want to store these starchy vegetables in a cool, dry, dark place. This keeps potatoes from sprouting, which is facilitated by sunlight and moisture. Sprouting your potatoes won’t result in more potatoes, just the added chore of trimming off the sprouts (which taste terrible and have some potentially harmful compounds in them).
Corn
Corn isn’t really a vegetable—a story for another time—and it doesn’t really belong in the fridge. But that doesn’t mean that you can’t call it one...or put it in the fridge. Putting corn in the fridge isn't going to hurt it per se, and it may keep it fresher longer, but if you're going to use it within a day or two you might as well leave it out and free up some fridge space.

Stone Fruit
Like tomatoes, putting stone fruits—think plums, peaches, and cherries—in the fridge can make their flesh go mealy. So if you want that incredible, silky, juice-dripping-down-your-chin bite, leave them out on the counter.
Pineapple
Once you pick a pineapple, it doesn't get any riper, so you should try to buy a perfectly ripe pineapple with the intention of eating it sooner rather than later. That also means that you should just leave it at room temperature—keeping it in the fridge isn't going to have an effect on its ripeness.
Melons
You could put melons in the fridge...if you really wanted to. But we prefer to eat melons at room temperature, so the flesh is as soft as possible. Changing the temperature of the melon will tense up the interior, possibly making it a tad less succulent.
Now, let's use those room temperature tomatoes:
Cheap? Yes. Tasty? Yes. Easy? Yes. Simple? Yes. Versatile? Yes. Should we start? Again, yes.
