Bacon Milkshake?! It's Happening at Jack in the Box

It's probably safe to say Michelle Obama wouldn't approve.

Fast food chain Jack in the Box is offering a new sweet treat that will likely delight as many people as it horrifies: a bacon milkshake.

It's part of Jack in the Box's new "Marry Bacon" campaign and will only be available for a limited time -- and if customers know to ask for it.

"The shake is not listed on our menus in the restaurants, so it’s more of a 'secret item' that people can order. Each restaurant is getting a very limited quantity, so we don’t know how long they will last," a Jack in the Box spokesman told the Huffington Post.

The ad contains a similar disclaimer, warning that "The bacon shake is limited as limited can be. There's no telling when it might disappear."

Alas, the shake doesn't actually contain real meat: According to the fast food chain's website, it's made with "bacon flavored syrup." It packs a caloric punch, though -- a regular 16-ounce size holds 773 calories and 40 grams of fat. A 24-ounce large one contains 1,081 calories and 54 grams of fat. If you want to check it out for yourself, it's listed as a "beverage" rather than a "dessert."

Oh, and if you were curious about what the "Marry Bacon" campaign is all about, here's an ad to clear things up:
