[SKU-181063]A white NCIS mug - "Gibbs Rule #3" says loud and clear that you're a fan of the incomparable Special Agent Gibbs and his colorful troupe. Former Marine gunnery sergeant Jethro Gibbs has a lot of wisdom from his years of fieldwork that he shares with his NCIS team and some of the rules extend well beyond the crime scene. The white ceramic NCIS cup holds up to 11 ounces and displays Gibbs' third rule "Don't believe what you're told. Double check," which reminds of the importance of not simply listening to all who claim authority.
