‎What Actually Makes a Joke a “Dad Joke”?
‎Before jumping into the knock-knock goodness, it helps to know what separates a regular joke from a true dad joke. A proper dad joke usually has a few key traits:
‎
‎Family-Friendly Vibes: Safe for everyone in the room—from grandparents to little kids. Nothing edgy, nothing awkward.
‎In-Your-Face Puns: The wordplay isn’t subtle or sneaky. It’s obvious, cheesy, and proudly so.
‎
‎Telegraphed Punchlines: You can usually guess where the joke is going… and yet, you still walk right into it.
‎Unshakeable Delivery: Dad jokes thrive on confidence. Groans, sighs, and eye-rolls aren’t failures—they’re proof of success.
‎
‎Nostalgia Factor: They bring back memories of simple times, backyard cookouts, and dads who thought they were comedians (and, honestly, kind of were).
‎
‎Combine all of that with the knock-knock setup, and you’ve got the ultimate recipe for corny humor that’s been making families laugh—and cringe—across generations.
