So, why would this Yuletide season be any different? Of course, it isn't.
If smartphone users conduct a Google search for "let's go caroling," your phone will transform into a Christmas karaoke machine!
The Easter egg works on both Android and iOS (but not with Internet Explorer on a Windows Phone--someone is grinching somewhere).
For non-WP-ers, there is a momentary delay for it to pop, but you'll receive a pull-down menu asking "Which carol would you like to sing?" with options for five holiday classics.
Clicking one will slide open a window that will allow users to prompt a cheesy musical accompaniment along with a highlighted real-time lyrics.
Caroling options include "Jingle Bells," Up on the House Top," "Deck the Halls," "O Christmas Tree," and "We Wish You a Merry Christmas."
It's probably a safe bet that right now some Google developers are plotting hidden gems for New Years.
