The heat-reactive surface reveals our exclusive Doofus University (tm) designs once the mug gets warm. Perfect for the unsuspecting doofus in your life. The ceramic cup will go back to its original black outside and white inside when it cools down. The C-shaped handle helps keep a sturdy grip. It comes in 11oz (0.33l) – plenty for that big morning cup of coffee and a hearty laugh.
