The new Facebook fad is the Mrs. Doubtfire Face for Suicide Prevention. You just upload a video of yourself jamming your face into frosting or shaving cream or something like that, and shouting "Hello!" just like Robin Williams does in the movie. Then you nominate three other people to do it.

The initiative was started by the American Foundation for Suicide Prevention, and even though they're not pressuring you to donate, obviously they'd be fine with that.
