I'm not sure if the humor translates, but there is a thread with this title on the Big Lebowski forum, which always makes me chuckle. I guess because I have a sick sense of humor but still view life as a precious gift even though I realize that our existence is fleeting.
It's not meant to be disrespectful to the newly dead; quite the contrary. The idea is to pause for a moment to honor the lives of those who have touched our lives in one way or another through some form of notoriety or celebrity status (be it music, the arts, entertainment, sports, politics, science, whatever).
This way, there won't be a need for threads like the one I started tonight: "RIP L.C. Geenwood" in which 63 people viewed, said "Meh..." and moved on.
This is not, however, the place to post if a relative or close friend has passed, for whom you wish to honor separately, or if someone like Michael Jackson or Princess Diana dies suddenly in a shocking way. More of a "some fuck or another" who added meaning to your life, but may or may not be known to others.
