Trying to explain 'the tragedy of the commons' to a repug at work when a idea popped out of my mouth, "Your free-loaders". Instantly every repug in the store is all over me, my simile is a mile wide and I can't stop laughing. Repugs want to have every possible use of common resources, while passing all the cost of maintaining those on to some one else. And they can't stand to acknowledge the fact of this behavior.
