The Rubik’s Cube has confounded us for years. Maybe the sandwich version of this puzzling brain teaser will do the same. The Rubix Cubewich contains cubes of pastrami, kielbasa, pork fat, salami, and two types of cheddar.
Note: Remember to play the Bug-Eyed Trivia Challenge every day. Why would you want to put a cube of pork fat in there?
