As I always say, a good pun is it’s own reword.
Dad jokes thrive on repetition.
Still.
You can say that again!
That.
I must have told you a million times to stop exaggerating.
Dad jokes thrive on repetition.
I’ve heard that before.
Then there are the dad jokes for when your kids become teenagers and they think they know everything.
“Have you heard of Murphy’s Law?”
“Yeah dad, ‘if anything can go wrong, it will’. Duh, everybody knows that.”
“Ok smart guy, have you heard of Cole’s Law?”
“Umm no, what’s that?”
“Thinly sliced cabbage mixed with mayo”.
I have a stoner dad his was "hay is for horses but grass is cheaper so grab a bowl and lets smoke some reefer "
Obligatory nitpick: “Everything that can go wrong, will” is actually Finagle’s Law. Murphy’s Law is “If there is a right way and a wrong way to do something, some fool will invariably do it the wrong way”. Murphy was an engineer, and his point was that systems should be designed so that there isn’t a wrong way.
I don’t get it. 
(I’m going, I’m going.)
Nitpick of a nitpick: That is actually Finagle’s Second Law.
Finagle’s First Law is: The perversity of the Universe tends to a maximum.

Q. How can you tell if a joke is a “dad joke””
