Celebrities - What's the Point of them, except to be proverbial punching bags by proxy?

Right. We humans tend to praise others for various and often indiscernible reasons. There are two predominant reasons:

1. Because they're filth and love to draw attention to themselves via the crudest way possible. Like me, except I tend to actually have something to say...
2. Because they know how to mince words, sensationalize, or have the charisma to get you to do something they want, even though they themselves have no intention of following through on their own words.

#1 is fairly straightforward: Read about a star who had pictures of their "special parts" photographed. or made a video tape engaging in "special acts" and deciding it should be released into the media for all to see?

#2 Aww heck, this is an election year and I've already bashed Hollywuss too much (for today, anyway)...

"Survival of the Fittest"

Who came up with that expression, and why?

First of all, who defines what is "fit"?

Could a cockroach be considered fittest?

Then comes "survival". This typically pertains to food, water, shelter, temporal endurance, and fulfillment of emotional needs (sex).

Cockroaches have lived long before mankind took over the planet. They will continue to endure.
Cockroaches will live under a rock. They think that is shelter.
Cockroaches will lap up water from a cesspool.
Which reminds me, cockroaches eat crap.

Cockroaches are vermin. What makes them fit to survive when we humans tell each other to go crawl under a rock, eat crap and die, and... well, I think you get the point by now.

One other thought... If it's to be fit to eat crap, who'll start a fast food franchise; put it in a bun? Imagine the adverts on television... I won't, thanks anyway.
