  <h2>What is a dad joke?</h2>
  <p>A dad joke is a short, clean, pun-based joke delivered with maximum confidence and zero shame.

Science has yet to explain why hearing one makes you feel briefly smarter and visibly worse at the same time.</p>
  <p>This site is a growing collection of the best dad jokes on the internet: one-liners, knock-knock jokes, and puns about animals, food, work, school, sports, tech, space and more. Every joke is family-friendly — the only thing at risk of injury is everyone's patience.
