National Junk Food Day comes round every July 21st, and every year people are encouraged to eat until their bellies are about to explode. Super healthy fun!

Since the “holiday’s” inception there have been all kinds of crazy junk food creations, so we put together a list of 10 of the most extreme.

Have you ever tried any of these horrific munchy masterpieces?

1. The KFC Double Down

Forget about buns, would ya? KFC had the balls to get rid of buns and replace them with chicken breast filets. In between the chicken buns? Bacon!

2. Pizza Hut’s Hot Dog Stuffed Crust Pizza

Well, that’s absolutely disgusting. This creation has never been available in the US, only in the UK and mainland Europe

3. Friendly’s’ Grilled Cheese Burgermelt

Here, we have two grilled cheese sandwiches as buns for a juicy hamburger. I think I could actually order this one…

4. Guy Fieri’s Cheesecake Challenge

This beauty is available at Guy Fieri’s American Kitchen Bar in Cancun. Cheesecake doused with fudge, pretzels, and potato chips. Yummmmmmmm.

5. Denny’s’ Fried Cheese Melt

It looks like a heart attack on a plate, but so what?!? Live a little. It’s a grilled cheese sandwich stuffed with fried mozzarella sticks. Boom!

6. Dunkin’ Donut’s’ Glazed Donut Breakfast Sandwich

The glazed donut will now be your bun, understood? Looks like Homer Simpson’s dream come true.

7. Jack in the Box’s Munchie Meal

Jack in the Box has a pretty eclectic menu, and it shows with their Munchie Meal. You get a HUGE sandwich, tacos, fries, and a big soda. I have a feeling this is geared toward a certain demographic that craves late night junk food.

8. Pizza Hut’s Cheesy Bites Remix Pizza

Pizza Hut did it again when it replaced the pizza crust with pockets filled with different kinds of oozing cheese. Because you always need more cheese, right?

9. Deep fried butter

You can find this concoction at state fairs and festivals across the U.S. of A! If you can eat it, you can deep fry it!

10. Bacon Bun Burger

It’s all about the buns, people. Yes, you’re looking at a burger with buns made completely out of bacon. WOW.
