If it's Tuesday, then it must be time for Timeflies!

The hip-pop duo have regularly made the day after Monday something to look forward to with their fun "Timeflies Tuesday" series of videos on YouTube. Among their last few efforts, the guys have remixed the latest hits by Miley Cyrus, Katy Perry and Lorde. But they reached into the recent past for their newest clip.

They take on Robyn's Grammy-nominated 2011 single 'Call Your Girlfriend' in their latest video, adding a dose of rap to the electro-pop of the original.

The clip shows rapper/singer Cal Shapiro and producer Rob "Rez" Resnick hard at work in the studio and performing onstage during their current Warning Signs tour. It also features plenty of behind-the-scenes and backstage antics.

Don't miss the bonus material after the credits -- let's just say that it's a safe guess that the guys are Boston Red Sox fans!
