I'm saying I don't recommend it, but I'm also saying I already ate two of them.
Immediately After Eating It:
While the sandwich is undeniably dense, it's still very small, about a fistful of chicken all told. Even though I was full, my body still wanted more food because my mouth isn't used to not chewing after, like, four minutes of eating. Make sure you order a side dish, and most KFC's come equipped with a lawyer on retainer, so make sure he's there to help you make out your will.
Where You'd Get It: McDonald's.
Why You'd Get It:
The work of Benjamin Libet in the field of Neuroscience supports the idea that free will is just an illusion, and that we have no real agency over our actions. You do not run your own life. Everything is predetermined, and we are bumbling, stumbling meat puppets that eventually die.
What is it?
The story behind the McGangBang is actually pretty cool. It's gotten virtually no attention in the press and has gained popularity over the last few years strictly by word-of-mouth and Internet forums, and it's still relatively underground. Sure, people have whispered about it and its history has been covered in exhaustive detail, but it hasn't quite reached the mainstream yet. It's only a matter of time before someone in a movie or TV show or popular and influential comedy megasite mentions it and then it'll just blow up. Here's how it works: You take an ordinary McDouble off the dollar menu...
...then you take an ordinary McChicken off the dollar menu...
...and you shove the McChicken inside the McDouble. Right in between the patties, just wedge that McChicken in there, so you have one tall super sandwich for just a few bucks. Get an order of fries because we all die in the end anyway.
There are actually a few different schools of thought regarding how many buns of the McChicken should make the transfer. Some say both, some say just one (and within that group, there are two separate camps, those who vote bottom bun and those who vote top). I've had the McGangBang several times using every variation of bun placement (because the futility of human existence weighs on me constantly), and I prefer the single bun (top), though they're all perfectly acceptable. What is not acceptable, however, is a total lack of McChicken buns. You need at least one in there, or you're just an asshole eating a stupid sandwich for jerks.
This is tricky, because a McGangBang isn't officially on any McDonald's menu. Maybe someday it will be, but I think the day we add an item called a "McGangBang" to a list of things we're pretending are food is the day the Earth will physically expel all human life from the planet. While it's not on the menu, you can obviously just get a McChicken and McDouble separately and put them together yourself (like a freakin' servant, but whatever).
Now here's the cool part. Some McDonald's establishments are aware of the McGangBang trend so, if you ask for one, they will serve it to you, fully assembled. Not always, but there are a few cases. There's a problem, of course, because you'll never know for sure if your McDonald's is aware of the trend until you ask. And if they aren't aware, then you're the fat idiot who just said "McGangBang" while anticipatory drool oozed from your mouth.
Get ready for a lot of embarrassment if you want to order it by name, is my point. I found one here in Southern California that will serve up McGangBangs on demand, but I'm not going to tell you which one because, hell, no one told me. I drove around to six different McDonald's asking for McGangBangs and got stunned silences and panicked looks before I found one that knew what I was talking about.
