My dad joke arsenal has peaked
"I'm reading a book about anti-gravity. It's impossible to put down."
"Why don't scientists trust atoms? Because they make up everything."
My kids groan every single time but I see them laughing like 2 seconds later. Mission accomplished.
The "I see them laughing" is the whole thing. They're groaning but they're also getting the format and the timing. That's literally how humor develops in kids. You're not cringe, you're teaching comedic structure lol
