If you've heard about the Ice Bucket challenge, you know it's the viral video challenge that raises awareness for the ALS association.
A new trend is the 'Doubtfire Face for Suicide Prevention', which is aimed to raise awareness about suicide prevention.
In memory of the late Robin Williams, challengers post a video of themselves smearing shaving cream on their face like his character Mrs. Doubtfire.
Then, the challenger must say "Hello" like Mrs. Doubtfire did in the movie and nominate people afterwards for the challenge to continue to spread awareness.
The challenge was started by the American Foundation for Suicide Prevention and people who upload videos are encouraged to use hashtags such as #RobinWilliams or #SayHelloToSuicidePrevention.
