'Tis the season for knitwear! So we’re celebrating sweaters of all shapes and sizes. Did you know that the ugly Christmas sweater trend got its start over a hundred years ago? Or that American soldiers in WWI had beef with amateur knitters? We cover all that and more, including the most expensive sweater ever sold and delightful facts about sweater-loving celebrities like Mr. Rogers, Weezer, and… Sting? Look, if this episode doesn’t give you the warm fuzzies, we don’t know what will.

Show us your best, weirdest, and/or ugliest sweaters! Tag us on Instagram @parttimegenius.
