Gum - Never work with friends or colleagues
Gum with a message. "Never work with friends or colleagues." Back side says "Be punctual. Wear safety goggles. Stop taking stupid pills. No shouting. No swearing. Don't be a douche bag. Keep coffee breaks to 15 minutes. Wash hands after using restroom. Always leave your balls and pride at home. Take a bath once in a while, for God's sake."
