The most efficient advice ever given, available in mug form every single morning. The "Don't Be Dumb" funny ceramic coffee mug features Pacific Northwest artist Sherrie's original watercolor art on a large 15oz mug — the snarky coffee mug that delivers the complete entirety of useful daily guidance in three words. Dishwasher safe, generous handle, vivid print with lasting quality. This is the humorous gift for the person who cuts straight to it, the direct communicator who believes efficiency is a virtue, or anyone who has spent more than a moment wishing people would just take this advice. A perfect birthday gift for the most sensible person you know, a great coworker gift for the colleague with the clearest thinking, or a reliable Secret Santa pick that will absolutely land.
