While the world is still mourning the death of Robin Williams, mourners are using Facebook to spread suicide awareness. Here is how YOU can get involved!

All you do is upload a video of yourself recreating the scene from Mrs. Doubtfire where Robin Williams slams his face into a cake to make it look like he's wearing some kind of old lady cleansing mask and yells, "Hello!"

Then, just like with the cold water or ice bucket thing, you nominate three more people to do it.  But unlike the other video challenges, there isn't a request for a donation if you refuse the challenge. The challenge was started by the American Foundation for Suicide Prevention. Click here to see some videos that have already been posted
