Hongbin Jeong and Nadiah Koh get festive as they unpack a Christmas chart twist: Mariah Carey’s All I Want for Christmas Is You has been dethroned by Wham!’s Last Christmas. Is the Queen of Christmas losing her crown, or still winning where it counts? They also dive into a viral story from South Korea, where a 20-year-old LG air conditioner turns out to have a logo made of pure gold,  sending people scrambling to check their old appliances. And to wrap things up, a TikToker tests which country has the cleanest streets by walking around in white socks, with Singapore, Japan and China all in the running.
