It's the country's reigning No. 1 hit on the Hot 100 Billboard chart, and one U.S. lawmaker apparently likes it so much that she participated in a summer intern video project, dancing to Carly Rae Jepsen's "Call Me Maybe."
The YouTube video, which was posted June 29 by the account " LorettaSanchezLive," begins outside Rep. Loretta Sanchez's Capitol Hill office, as the opening bars of the popular song begin to play.
The camera enters, showing staff working hard in tight quarters in the Longworth House Office Building when Sanchez, D-Calif., is finally revealed behind her desk trying to figure out the choreography parodied in a viral video by the Harvard baseball team.
Until the song's chorus, Sanchez is struggling to get the timing of the moves down when suddenly three interns pop up from their concealed position in front of the lawmaker's desk to demonstrate how it's done.
Sanchez, 52, then catches on quickly, performing the routine in unison with her young colleagues.
After about one minute, she is shown seated casually at her desk when she says, "Everybody have a safe and Happy Fourth of July."
The video was shot Friday as the office winded down the busy week and gave the interns a break from their regular duties of answering phones, leading tours of the Capitol and helping sort mail, according to a spokeswoman.
"The video seemed like a great way to inject lightheartedness into the week and welcome the holiday weekend," Sanchez's press secretary, Adrienne Watson, told ABC News. "We appreciate our interns so much. We want them to learn a lot, but we want them to have fun, too."
"Loretta has a sense of humor," she added. "Most Americans can't escape hearing this ultimate summer song. Our interns saw the baseball team's spoof and showed it to the congresswoman and then they spearheaded their own spoof."
There are no other intern video projects posted to Sanchez's YouTube account. The clip was first reported by National Journal.
