Dad jokes hit different when they groan
Nothing beats that sound of your kid's combined groan when you hit them with a good dad joke. Like today my 10 year old asked what time it was and I said 'time to get a watch' and the whole family just stared at me. But I saw the corners of his mouth twitch. He was fighting the laugh. I know I got him.
The synchronized eye roll from multiple kids is even better than the groan. That's when you know it's a quality dad joke.
