Marketing and Scifi have a problem in common - coming up with cool sounding names for made up stuff. It is perhaps no surprise that so many hair care products sound exactly like planets from Doctor Who.
Take my little quiz to see if you can tell the difference. I've tried to be fair and use only non-obscure planets from the TV show, ignoringas one probably should the seventy thousand novels, comics and audio plays.
Well, that was a total waste of time. Be thankful you only took the test instead of writing it.
