April 7/Atlanta/CNN.com --Is fat fare at fast foods going too far?

In the midst of first lady Michelle Obama's campaign against child obesity and chef Jamie Oliver's prime-time TV initiative for cleaner cooking, a chicken chain is crowing about some aggressively fat-laden fare.

KFC's long-rumored Double Down waddles into stores on April 12, boasting an ingredient list that prompted a copywriters' caveat on the product's web page that it is "Real! No fooling."

The bun-free ("so meaty, there's no room") sandwich features two pieces of bacon, two slices of melted cheese and "Colonel's Sauce" -- which KFC officials said is a "zesty mayonnaise" -- slathered between two chicken filets, either original recipe (540 calories and 32g of fat, per KFC.com) or the slightly slimmer grilled version (460 calories and 23g of fat).

Response from around the Internet ranges from Consumerist.com's "mysteriously tempting (and potentially lethal)" and the Huffington Post's "going too far" to the Lincoln Journal Star's "fast-food-related crimes against humanity," but KFC's gamble on the Double Down's appeal to calorie scoffers seems downright chicken in light of a new baseball concession pitched by the Toledo Mud Hens.

At a March 24 press conference, V/Gladieux Enterprises, the catering company that services Fifth Third Field announced a sundae, "Which is 15 scoops of Toft's ice cream served in a full-size souvenir helmet for $25. It will serve 1 to 8 fans; you can enjoy by yourselves if you love ice cream or share with family and friends."

A solo at-bat with the Fifth Third Fanatic Freeze would average 2,325 calories, based on a 0.5-cup scoop size -- before a grand slam addition of whipped cream, hot fudge, rainbow sprinkles, peanuts and cherries.

Dessert not on the roster? That same full-sized batting helmet can switch-hit as a bowl for cheese-drenched Fifth Third Nachos -- a perfect snack after running the bases the approximately 341 times it would take a 150-pound person to burn off the aforementioned ice cream.

The Mud Hens and KFC's Colonel are hardly the first food vendors to flip a big ol' bird at the calorie cops. Here are a few that have flown outrageously afoul over the past few years.

Burger King: Meat'normous Omelet Sandwich
The King did not just come slinging a brand new portmanteau of "meat" and "enormous" with this limited-time item. Starting in 2005, the now-discontinued breakfast bomb came loaded with two eggs, one sausage patty, two slices of ham, three slices of bacon and two slices of American cheese on a long, toasted bun. That is 770 calories, 47g fat and a near guarantee of waking up in a cold sweat from a food coma nightmare starring that creepy, plastic-masked King.

Taco Bell Chicken Ranch Taco Salad
A salad sounds pretty sensible, right? Depends on what you mean by "salad." A cheeky 2009 commercial for the chain's crispy tortilla-swaddled heaps of rice, beans, cheese, meat and additional tortilla strips defined the dish as "technically a salad" due to the presence of some lettuce shreds buried under the other ingredients.

The Bell's 54g of fat Chicken Ranch Taco Salad is the second most caloric item on the menu, weighing in at 910, but comes served, improbably, with reduced fat sour cream.

GCS Ballpark: Luther Burger Baseball's Best Burger
In 2006, Sauget IL's Frontier League baseball team, the Gateway Grizzlies paired up with Krispy Kreme Donuts to pay homage to the Luther Burger, popularized at Atlanta's Mulligan's restaurant.

The multi-meal mash-up consists of a thick, bacon-and-cheese-topped burger patty, stuffed inside a sliced, glazed donut. It's estimated to weigh in around 1,000 calories with 45g of fat. It was declared by professional face-stuffer Adam Richman of Travel Channel's Man v. Food to be "deliciously psychotic."

Hardee's: Monster Thickburger
Hardee's CEO Andrew Pudzer told CNBC upon the Thickburger's 2004 debut that the 1,320-calorie, 95g-fat sandwich was "not a burger for tree huggers." After downing two 1/3-pound beef patties, four strips of bacon and three slices of American cheese stacked on a mayonnaise-slathered bun, it seems unlikely that many eaters would be able to summon the strength to walk outside to a wooded area -- let alone sling their arms around it.

The chain also offers a bun-free, lettuce-wrapped 1/3-pound Low Carb Thickburger, should one of those wacky health nuts insist upon coming along for lunch.
