DETAILS

"Master of Bad Arguments" — say it without saying a word. A funny coffee mug and gift for anyone with a job.

Who it's for: the coworker who argues just to argue, the stubborn manager, the devil's advocate friend, or yourself — buying it for yourself absolutely counts.

When to give it: Secret Santa, promotion, white elephant — or any meeting that turns into a debate.

Why it works: A joke they'll see before their first sip, every single day — the rare gift that actually gets used.

  • Printed in full color, the same design you see in the photos
  • Dishwasher and microwave safe — the joke keeps its shine
  • About 4.6" tall, 3.4" across the base
  • Free US shipping on every order, no minimum
