Millions of Americans watched on Friday as Donald J. Trump became the 45th President of the United States. And if they were listening carefully, they might have heard someone screaming out “Baba Booey” just seconds before the new commander in chief was sworn in. Press play (below) to hear it for yourself.

Several Stern Show superfans took to Twitter to say they definitely caught the classic catchphrase being shouted out at the Capitol Building, including Sarah Silverman. Check out her tweet (below).

Did anyone else just hear a bababooey — Sarah Silverman (@SarahKSilverman) January 20, 2017

Sarah is no stranger to Booey bombs – she delivered one of the most epic “Baba Booey’s” at the 2016 Democratic National Convention, concluding her speech with a special nod to Howard and the Stern Show.

Here’s what others are saying about the possible presidential Baba Booey shout-out:
