Chicken fries are probably the most unholy culinary creation of all time. Have you tried them? I got them once expecting chicken strip in fry aspect ratio, but somehow they made a chicken-based sponge and deep fried it.
I haven't had them, but I did have, on a dare one time, a KFC Double Down, which is a bacon, cheese, and mayonnaise sandwich for which the bread has been replaced by two pieces of fried chicken. It is not as scientifically dubious as chicken fries, but every bit as offensive to humanity.
It might have been In Search Of, it might have been Burke's Connections. They were standing in the desert somewhere showing erosion control. When all you have is oil, they said, you use oil for a lot of things you wouldn't normally. Like erosion control. Dig it out of the ground and charge the Infidel $40 a barrel for it... or spray it on the dunes to keep them from moving. That, to me, is American cuisine. The Iranians (or Saudis, can't remember) would probably have killed for dandelions and the ability to keep them alive. But they had oil and nothing but oil so they kept the dust down by hosing it with crude. The British have us beat, I guess, but they're a country that told their proletariat to eat nothing but potatoes. The Double Down is an Irish Potato Famine of protein subsidy.
My path doesn't cross fast food very often. The kid's grampa likes to go to McDonald's so she'll go there with him (or did "before the sickness" as she puts it) and there's a Wendy's on the way home that has gotten maybe 3 orders out of us in 5 years. But if there were a Burger King in my sphere of influence, I probably would have also expected chicken strip in fry aspect ratio, and then I would have kicked myself for not recognizing it as a bizarre funnel cake mutation.
