What are Danish Butter Cookies?

What are these Danish butter cookies? I've never heard of them! And I certainly wouldn't be obsessed about something I know nothing of! Honestly, someone should get me some of these Danish Butter Cookies (in a blue tin), so I can try them out. I bet they are good. They probably melt in my mouth, and fill my tummy with deliciousness. And I bet the original Danish cookies are the best, not the other kinds where they experiment with weird things like chocolate. Who ever heard of chocolate? Hmm, obsessed with Danish Butter Cookies! Ridiculous!
