White Castle Chowder And 10 Other Fast Foods You Should Never Order

White Castle Chowder. Need we say more?

Everyone has a fast food guilty pleasure -- something so bad, it's good. Maybe it's a McFlurry with all the toppings. Maybe it's a Triple Burger from Wendy's. Whatever it is, we support your guilty pleasure -- unless it falls under the "items you should never ever touch with a 10-foot pole" category.

Whether it's a specialty item that comes but once a year (we're looking at you, Shamrock Shake), a limited-time-offer or a menu staple, some food simply doesn't belong in certain fast food establishments. It certainly has no place in your stomach.

Thankfully some items, like McSpaghetti, get discontinued when chains come to their senses. Still, there are plenty of monstrosities lurking on fast food menus everywhere, so you'd better beware. If you know what's good for you, you'll avoid these fast food items at all costs, because they're downright offensive.

Taco Bell Mexican Pizza

The lower level of meat is enough to make us never want to eat food again. The "sauce" looks like ketchup, and the spam-like cubes on top are supposed to be "diced ripe tomatoes." We rest our case.

White Castle making another appearance here... Why "rings?" Why?
White Castle Shrimp Nibblers
White Castle
And again with the name, White Castle. Nibblers? Do better. It might have been passible, but then they encouraged you to eat your Shrimp Nibblers with your Mac & Cheese Nibblers.
McDonald's Shamrock Shake
The color alone makes us gag, and so does the not-so-minty, "creamy" flavor.
Denny's Clam Chowder
Chowder, GO AWAY.
KFC Famous Mashed Potato Bowl
Patton Oswalt called it the "failure pile in a sadness bowl." Need we say more?
