Get into the holiday spirit with this newly discovered Easter Egg from Google. It’s a simple one that requires you to fire up Google Search and invite the personal assistant to go caroling with you.Just launch Google now by speaking “Ok, Google Now” or by launching the Google Search app manually. If you are a hands-free type of person that used voice commands to fire up Google Now, keep going with your voice by simply saying “Let’s Go Caroling.” If you launched the app manually, you will have to tap the microphone to activate the voice prompt and then say the Easter Egg phrase “Let’s Go Caroling.”

I won’t spoil the fun by revealing the full Easter egg, but suffice it to say you should warm up your singing pipes with a few lines of do-re-mi first. This isn’t the first Android easter egg — there’s a recent one in Android 4.4 KitKat and another one in Google Search.
