They may not be printed in big bold letters, or posted on the window of your favorite fast food joint, but these menu items really do exist; and if you're brave enough, you can get your hands on one of these today right here in Tyler, TX.

You'll want to brace yourself for some of these - and you might want to break out the Tums for others. Let's jump right in:

1. Burger King's 'Suicide Burger' 

The name is a bit intense...but so is what you get. Burger King has that flame-broiled goodness you can smell from the street, but would you want 4 patties? If you answered yes, here you go - 4 patties, 4 slices of cheese, bacon, and the burger joint's secret 'stacker' sauce. Check it out here.

2. McDonald’s “The Land, Sea and Air Burger”

If you can't choose between a burger, a fish sandwich, or chicken sandwich, the golden arches say you can try all three! Did anyone else just feel a little intimidated? It's the grandest, or most questionable anyway, surf and turf of them all: a Big Mac, a Filet-O-Fish and a McChicken on a three-layer Big Mac bun.


 

3. Chipotle's Quesarito

If you're a fan of burritos, this one isn't a big shock. But what if I told you the wrap isn't a tortilla, but instead...a QUESADILLA? Like the guac, this is a fan favorite off the secret menu. However, maybe because it's hard to fold, Chipotle charges an extra $3.50 for this secret-menu upgrade.

 

4. Taco Bell's 'The Hulk'

Did you know that you can add guacamole to literally anything at Taco Bell? Apparently, some folks don't. Adding guac to a bean-and-cheese burrito will automatically transform your boring lunch into the Hulk! This looks amazing. Seriously. Give. Me. The. Guac.

 

5. Chick-Fil-A's Chicken Quesadilla

Now before you go running to this happy place, this one isn't always available at all locations. In fact, Chick-fil-a seems to not know of its existence. It's simply CFA's char-broiled chicken and melted cheese in a large tortilla. If you're really trying to change things up at Chick-fil-a, the company has a whole list of secret items you can make yourself!

Ok, brave souls! You have to let me know which one of these you try!

Meanwhile, I'm grabbing guac.
