Is Rock Paper Scissors the answer to everything?

I keep seeing Rock Paper Scissors pop up in random places on TV and in movies...

There was a helarious bit when I was rewatching season 1 of arrested development with a giant rock and a giant pair of scissors... then the other day I was surfing around and I saw a whole DVD game of rock paper scissors... http://www.fistsoffire.com

So really, is it taking over? does anyone actually use it in real life?
