Funny Work Mug — "Master of Bad Arguments" (MBA) Coffee Mug

"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.
