Google has created a very festive Easter egg for smartphone users. On your mobile browser, simply do a Google search for [let’s go caroling] and a menu will pop up allowing you to select from five different carols and turn your smartphone into an instant karaoke machine.
There are five carols currently included, "Jingle Bells", "Up on the House Top", "Deck the Halls", "O Christmas Tree", and "We Wish You a Merry Christmas". When you select one, the cursor bounces along with the lyrics just as it would on a karaoke machine.
The Easter egg isn't Android specific. It works on all mobile browsers.
Google has a long history of doing hidden surprises in their search results, such as [do a barrel roll], which produce "Star Fox" inspired results. Typing in [google in 1998] allowed searchers to see Google search results as they appeared back in 1998. Google has also included Easter eggs in search results for [the answer to the ultimate question of life, the universe, and everything] (the answer is 42), as well as [define anagram}(“Did you mean nerd fame again”?)
