Animal Farm by George Orwell
I'm sure if Animal Farm were re-written tomorrow, or made into some hammy Hollywood production, this illustration might become reality. Well, movie reality.
If you aren't familiar with this classic story, here is a very succinct summary:
Some farm animals get fed up and overthrow some farm humans.
I don't really think that's a spoiler, but I won't go any further. It's a short book, OK?
I should probably also explain the text. "Pigs are walking," is a great quote from the novel. Applied to society (and not in the farm animal context of the book), it is used to describe people or things that are trying to be something that they are not. So, a "hipper" version would involve some hip activity, such as hula-hooping or candy-striping. Or texting.
