Fans of the Five Guys burger chain will be pleased to hear that you can absolutely prolong your order time now that they're testing customizable milkshakes. That's gotta be wonderful for the lines. Though, hey, bacon and Oreo milkshake!

Customers begin with a vanilla base for their milkshake. They're then given the option to mix in as many topping options as their artery-clogged hearts desire. Some of the more notable toppings include salted caramel, coffee, Oreo cookies and of course bacon.

Not sure yet if it's a Highlander type situation where the fewer ingredients you choose, the more you'll get or if each shake will have a fixed amount. Regardless, customers can now relish in the fact that their entire meal is customizable. In a few years, they'll probably let us choose how to cook our burgers and fries as well.

The milkshakes are currently being tested at select Five Guys locations, specifically in the East Coast.
