[Video] Office Hours: Ask Me Anything About SQL Server, Mink Edition


In this episode, I’ve got my own question: what’s this animal running around at my feet? Commenters on the YouTube video explained that it’s a mink. They were imported into Iceland in the 1930s for their fur, and they escaped out into the wild. The country’s been trying to reduce their population, and they’ve even been part of the COVID19 news.
