Every executive knows, you’ve got to delegate. That’s why this World’s Best Boss coffee mug has been engineered to free up your hands for sipping coffee and other important boss tasks, by printing a middle finger on the base. With every drink you take you also flip off the whole office, reminding them what it takes to be at the top: Attitude, humor, and a bad-ass mug. Not a boss yet? Sip this mug as an underhanded compliment to your supervisor!
