I liked James Taranto's metaphor:
ObamaCare, for example, was described as a fiscal perpetual-motion machine: By vastly expanding government control over medicine, it would reduce costs and provide care to everyone.
If you believed that, I’ve got a bridge in Brooklyn I’d like you to buy (well … as a matter of fact … politicians in the state of New York have bought into the perpetual motion machine many times … so they’re probably entertaining offers on the bridge).
