What guy takes his granddaughter to the aquarium and spouts fish puns all day? Who accompanies her to a children's recreation center and almost faints in the bouncy house? And which grandpa goes to the White House Easter Egg Roll so he can introduce his precious pumpkin not to the president but to Peppa Pig? Jerry Zezima, who also gives grandfatherly advice to Prince Charles, peddles his granddaughter's preschool fundraiser, introduces her to the neighborhood ice cream man, and does lots of other fun stuff, both with and without his adorable princess, which may explain why she is more mature than he is. In "Grandfather Knows Best," nationally syndicated humorist Jerry Zezima writes about the joys of grandparenthood and the things one man will do for the little girl who has captured his heart.
