Jack in the Box is now serving a Bacon Milkshake. Yes, it's real, and yes, they are hoping it will cause some sort of bacon-fueled mass hysteria, so it's "as limited as limited can be." Denny's produced a Maple Bacon Sundae for their Baconalia promotion, so it's not unheard of for a chain to add bacon to dessert, although word on the street is the Jack in the Box shake uses bacon-flavored syrup and not actual porky goodness.
The shake is part of a new campaign that asks the question: If you like bacon so much, why don't you marry it? They mean literally: the ad below features a bacon wedding that ends with the oh-so-romantic words "You may eat the bride."
