Google honored thousands of fathers today with a Google Doodle displaying a tie and encouraging people to use Gmail to call their dads.

Unlike some of the recent Google Doodles that came with fancy graphic, ability to record music and playback, or animation, the Father’s Day Doodle is very simple - a picture of a brown tie with dots replacing the letter “L” of “Google”. Clicking the banner will give a search result with the keyword “Father’s Day”.

Meanwhile, Google is encouraging people to give a call to their dads using their Gmail service. On the main page of Google under the search box, Google inserted a line with a link that says, “Dad. Father. Pops. No matter what you call him, call your dad from Gmail.”

Clicking the link will direct the users to go through a customized page that introduces the Google Voice, which allows users to call other phones directly from Gmail.

Making a phone call from Gmail is free within the U.S. and Canada and other international call is “super cheap,” according to Google.

If you did not have the chance to give your old man a call, it is not too late. However, be sure to check your settings before you try the Gmail phone call service so that your speaker and audio works.
