It's hard to precisely discern the difference between a regular dumb joke and a dad joke. It's something that you just recognize when you see it. Does the joke involve cars, boats, or wives? Probably a dad joke. Did a middle aged man make a pun about his meal to the server? Definitely a dad joke. That said, you certainly don't have to have kids to enjoy a good (or bad) pun. Just channel your inner dad and vibe with these corny memes.
