Start each morning with a piping-hot dad joke. He always has the best advice for any situation, and screaming kids don't faze him. Kind, caring, and full of love, he's the coolest dad there is, but there's more to him than meets the eye-just like this color-changing mug, which shows ""Cool Dad"" when empty or holding a cold drink and reveals ""Hot Dad"" when a warm beverage is added.
