As a father of three, by far my favorite Dad Joke has to be claiming things as my "Dancer Names". I have at least one or two a week.
It's whenever someone says something in conversation which sounds like it could be a Stripper name. Off the top of my head, here are some I've used:
"Yummy Cupcakes", "Pansy Taboo", "Stamen Fuzz", "Dark Almond", "Squeeze Bacon", "Bolt Upright"
I'll often follow it up with a hint as to what that show may just be like.
Guy on television: "The bee is now covered in stamin fuzz..."
Me: "'Stamen Fuzz' is my dancer name. Quite a show; not for the allergic."
