What I Love about Grandpa Fill in the Love Book (Other) (ISBN-13: 9781683490494)

KNOCK KNOCK is a maker of products that bring wit, heart, productivity (and occasional light profanity) to everyday life. Our pads, planners, journals, and books help people accomplish their goals, express their feelings, and laugh at the absurdity of modern existence.

We live by (at least) two mottos: "We Put the Fun in Functional" and "Make a List--You'll Feel Better." We consider list-making and laughter to be essential forms of self-care. (And, obvs, we love mottos.)
