Julia lied about the Carbon Tax, therefore she became Ju-Liar. Geddit?
What I don't get though, is why is it called a Carbon Tax? Clearly they are taxing carbon dioxide, not carbon.
The cynic in me would say they use the term "Carbon" to conjure up images of dirty, sooty chimneys because if they talked about carbon dioxide, the great unwashed would correctly start asking about what plants use to photosynthesise and what comes out of their mouths when they exhale.
