Like many people, Professor Brian Cox has a Christmas tree up, but unlike many people, his is in the shape of Darth Vader. 

Casually revealing his Star Wars-themed decorations on ITV's This Morning, Cox swiftly went to Twitter afterwards to post a picture of how he's celebrating Sithmas. 

The trick is to not buy a specific Darth Vader tree off the shelf - though there's no doubt that'll be a thing soon enough - but to buy another tree and Darth it up. 

"We bought a black Christmas tree and decorated it as Darth Vader," Cox explained, in the process revealing there are such things as black Christmas trees. 

That professor - always full of interesting information, eh?
