When the Washington Nationals walked down the south side steps of the White House Monday for a ceremony honoring their World Series win, they were accompanied by a musical number not commonly played by the U.S. Marine Band. Yes, they walked out to singalong tune “Baby Shark.”

For many Americans not following the Nationals season, the song came out of left field when the baseball team made the World Series.
