The patients and staff at the Childrens Hospital at Dartmouth-Hitchcock Medical Center have hit the Internet big time.
Their video of them lip syncing to Katy Perry's "Roar" has been viewed just over 1.2 million times on YouTube, as of Thursday afternoon.
The hospital produced the video for its CHaD HERO Half Marathon & Ripcord 5K.

The Huffington Post has picked up the story, as has BuzzFeed, just to name a couple examples.
