When you get three dad joke books for Christmas, that's a sign...they want more dad jokes?
Examples:
Someone threw a bottle of omega 3 pills at me.
Luckily, my injuries were only super fish oil.
I saw my ex-wife across the museum hall, but I felt too self-conscious to say hello.
There was just too much history between us.
Grandpa: I have a "dad bod."
Dad: To me, it's more like a father figure.
