It's mashed potatoes in a f*cking Slurpee machine.
First found by The Clearly Dope's Tumblr page, the machine only charges $1 for you to fill up a huge bowl with the mashed potatoes. And it's only $2 if you want to add your Big Gulp to the “meal.” (Well, except in New York. Thanks, Bloomberg.) There's also an option to add chicken gravy on top of the potatoes for no additional fee. Give it to me.
