If you’ve hopped on the very merry Orange is the New Black TV bandwagon – and if you haven’t, you should – nothing will catapult you into the silly season faster than this going viral video. Danielle Brooks, who plays Taystee in the show about life in a women’s prison, sings alongside Uzo Aduba (Crazy Eyes in OITNB), and the two bust out your favourite seasonal tracks. And it's all to raise money for charity, making the three feel-good minutes even more worth watching. Vid of the season? Case closed!
