And it's only available in limited markets: Virginia and Pittsburgh.

I'm just outside Richmond, in Powhatan, Virginia, at this KFC-Taco Bell combo, and I'm gonna give it a try.

Could I get one fried-chicken-doughnut sandwich?

So, I was not allowed to film inside.

But I got a bunch of these sandwiches.

So I'm gonna take them away from the store and give them a try.

OK, I'm very excited to check this out.

"Think of this as a tiny treasure chest filled with CHICKEN TREASURES." - Col. Harland Sanders.

I am a KFC guy.

There is nothing better to me than the idea of just a bucket of KFC.

I want to like this.

In terms of doughnuts, Krispy Kreme is the only doughnut that I recognize as worthy of being called a doughnut.

That's really gonna be the big test here.

So, let's get into it!

Wow, so that's a big doughnut.

Just gonna take it out.

It's so messy.

It's a beautiful piece of fried chicken in between two glazed doughnuts.

And these are looking more like Dunkin' Donuts.

These are way more bready than Krispy Kreme, which is my favorite.

So, I'm just gonna get right into it!

Oh man, I like it.

I gotta tell you, I was worried about this.

But I really like what's going on right now.

The chicken is thick. It's juicy, succulent.

I'm usually not that big of a fan of sweet and savory.

When I first bit into it, I was like, oh boy, there's the doughnut, and all I taste is doughnut.

But then, very quickly, after the first bite, that chicken kicked in.

One concern here: I've got a lot of, like, overhanging doughnut.

There might be a little too much doughnut in this sandwich.

Maybe the chicken patty should've been a little bigger.

We have a lot of excess doughnut flop going on.

There don't appear to be any other ingredients in this.

And the simplicity of it is pretty intriguing.

There's no weird syrup or chipotle, mayo or anything like that.

That was a pleasant surprise.

I really enjoyed that, but I feel, like, sort of irresponsible to ingest that many calories.

Despite how fun it is...

But, for like a one-off, I think that people should give this a try, especially late at night.

Hopefully the rest of the country gets a chance to experience what I just had.

The Colonel kicked it up a notch.

KFC, old franchise willing to take new chances, new risks.

I'm gonna lay down and take a nap.

Because I'm going into this weird chicken-doughnut coma, where I'm kinda hopped up on the sugar, but I'm also tired from just the overall consumption levels.

I don't know what I'm feeling, but it feels good.
