Well with the holidays Google developers insert yet another holiday-themed Easter egg. This time it is Christmas Carols. All you have to do if you are a smartphone user is run a Google search for “let’s go caroling.” When you do this your phone will turn into a karaoke box with classics like”Jingle Bells,” Up on the House Top,” “Deck the Halls,” “O Christmas Tree,” and “We Wish You a Merry Christmas.” The hidden code works on both android and iOS, but will error out if you use IE on a windows phone.
