Whelp, these videos are just too sweet to handle. Here's the original, by a 17-year-old named Zach Sobiech who was diagnosed with osteosarcoma. And above is the video that Rainn Wilson's Soul Pancake put together, with a bunch of celebrities (seriously, a bunch), as well as Zach's friends and family, singing the song to him.
"Clouds," which is about having to say goodbye due to a terminal illness, inspired hundreds of other kids and teens with cancer to make their own video in solidarity.
If you've got a dry eye after these, you may, in fact, be a robot.
