Does anyone know where Bernadette's duvet cover in The Cohabitation Formulation is from? あなた see it at the beginning when she's arguing with Wolowitz about him staying over. Thanks!

I'm sorry, I don't know. Just wanted to make sure あなた knew we weren't ignoring your question. But good thing あなた mentioned when あなた can see it, because I'd completely missed it the first time!
