Mining community Puns

I’m about to ask a friend of mine to Prom, and she’s an exchange student from Denmark. She’s also a huge fan of puns.

Thus, I’ve come to the finest community of Reddit in search of a good Denmark pun. What’s your best??

I recently joined a CSF - a community supported fishery. Once a week, I'll pick up a filet of freshly-caught salmon, a bag of shellfish, or other such delights from the Pacific Ocean and bring it home to my darling wife and children to much joy (or anguish, depending on who you're asking.)

You get to choose your pick-up spot, and I chose a location close to my office, so I could swing by on the way home; it's a nautical-themed bar, appropriate for such a business transaction. "Go to the bartender and ask for the fish", say the instructions; so I did, and he handed me the catch of the day. Gleaming white filets, glorious they were. Then I met a friend of mine, and after chatting for a little while, I went home.

"Jack," says my wife, "what took you so long? You should have been home an hour ago!"

"Sorry," I said. "I stopped by the bar, just for the halibut."
