7The dad joke is a delicate thing. Part knowing humor, part lack of humor, its only requirement is that it elicits not a laugh from its audience but the annoyed response: Daaaaaaaaad. Bad Dad Jokes wall calendar is a collection of so bad they're actually good jokes that are guaranteed to deliver a daily dose of groans and giggles all year long. Printed with soy-based inks on FSC certified paper, this 12 x 12 wall calendar features extra-large monthly grids that offer ample room for jotting notes, along with six bonus months of July through December of 2021. Also includes moon phases (CST), standard U.S. and international holidays.
