Steak umm Puns

Scene: Dinner for my mom's birthday at a very nice (expensive) restaurant.

Waitress: Your steak comes with a choice of the vegetable of the day or a twice baked potato.

Me: Are twice baked potatoes and refried beans prepared similar ways or is that just a naming coincidence?

W: Laughing Oh my God. Our bartender and I were just talking about funny "dad jokes" on reddit! I didn't expect to hear one in person. Do you use reddit?

M: Umm... Yeah... I actually follow r/dadjokes but I'm not a dad and

W: You should post that joke there!

I have no idea if she will see this but my wife said I had to let everyone know about a redditor interaction. I hope she does because the food was awesome and she was a fantastic waitress beyond being a fellow redditor.

I still have no idea if twice baked potatoes and refried beans have any link...
