Sorry for this one, but I couldn't help myself.
Rush Limbaugh vs. Michael Moore: conservative, drug-addicted, butterball versus liberal, well, I don't know about the drugs, but he is a butterball. One wears a suit and pollutes the radio waves, one dresses like a college student and pollutes (say some) the movies.
That stuff you're tasting at the back of your throat? That's bile.
