Every week Bostonist is dedicated to bringing you the most contagious Boston-based viral videos on the internet.

The sign of a truly strong virus is one that you catch, recover from, and catch again. So is the case with Massachusetts' own viral video star Bo Burnham. Boston Viral Video first caught on to young Bo's pun-full bedroom rap back in early May. As his catchy videos spread across the internet, the bigwigs at Comedy Central caught Bo fever and agreed to help Bo put out his debut EP Bo Fo Sho on iTunes.

To hype his new record, Bo unleashed "I'm Bo Yo" onto the internet, featuring some of his highest pun-to-rhyme ratios yet. (If you're at work, it would be a good time to put the headphones on now.)
