One day before the London Olympic Games opening ceremony on Friday, the 2012 USA Swimming national team posted a video of themselves lip-synching the hit "Call Me Maybe."

The song by Canadian pop star Carly Rae Jepsen has been an online monster since its release, and the swimming team's video is following in its footsteps, attracting more than 600,000 views in just 24 hours on YouTube.

Everyone watching the Olympics this year will hear about how hard it is for athletes to train early in the mornings and follow a proper diet. Those restrictions apparently don't prohibit some good old-fashioned karaoke, though, as about 95 percent of the team appears in the video, according to USASwimming.org. That includes Michael Phelps (who you can see most prominently in the beginning) and Ryan Lochte.

According to the website, the video effort was led by team members Alyssa Anderson, Kathleen Hersey, and Caitlin Leverenz as a way for the athletes to "blow off a little steam in their spare time." Almost all of the reaction on YouTube was positive, with nearly 11,000 likes recorded by Friday night. Most comments expressed support for the team -- and some made a plea for the U.S. basketball team to do a similar video.

The original "Call Me Maybe" video has almost 200 million views on YouTube and has been covered by everyone from the Harvard Baseball Team to the Star Wars characters.

Instead of making "Call Me Maybe" more unlistenable in the following video, the U.S. swimming team morphed from a comparatively anonymous group of athletes into one that appears very likable and easy to root for, which one can begin doing Saturday at 4:55 a.m. EDT, when NBC will air premilinary heats in multiple events.
