You tell me: Has man’s favorite food (bacon, duh) finally jumped the shark? The new Bacon Milkshake from Jack in the Box certainly will test your love for your favorite cured meat, and it’ll test your arteries too. The 16 oz. cup of this limited time treat – using the term “treat” very loosely here – delivers 773 calories and 40 grams of fat through your aorta. Apparently this creamy concoction isn’t even listed on the menu, so you’ll feel like an insider when you order it off the secret menu. A very tubby insider.
