Some people are way too comfortable.

This funny ceramic coffee mug features a charming vintage-inspired illustration paired with the perfectly blunt phrase, "Don't act like you know me." Equal parts sweet and sarcastic, it's made for introverts, socially selective people, and anyone whose facial expressions say exactly what they're thinking.

Whether it's your morning coffee, afternoon tea, or your daily dose of caffeine before dealing with people, this mug delivers just the right amount of attitude.
