Funny Shellfish Puns

I didn't even mean to make a dad joke, apparently after seven years of being a dad, it just starts to happen.

I was installing some shelves up on the walls over my computer desk. Having just finished marking the walls where I was going to insert the screws, I was now installing the brackets onto the boards.

From behind me, I heard my wife say, "How's it going?"

Me: "Well, it's shellfish."

Wife: "It's what?"

Me: "Shellfish. I'm still putting the mounting brackets on, so it's not a shelf yet. It's shelf-ish. Shellfish."

At least my daughter thought it was funny.
