Yet another Google Easter Egg: this time, one that only works on Android and iOS devices. Search for the phrase "let's go carolling" and you'll be presented with a selection of five Christmas carols you can sing along to, complete with on-screen lyrics.
Google isn't that fussed about spelling; you can skip the apostrophe in "let's" and use the US spelling of "caroling" if you wish. Admittedly, 'Up On The House Top' is not a song most Aussies give a damn about, but that's hardly embracing the festive spirit, is it?
