"These guys believe that a 350 billion dollar tax cut will stimulate the economy, and they are full of shit. Because they don't know what stimulates the economy. The economy goes up, it goes down, it goes up, it goes down, it goes up, it goes down, nobody knows why the fuck it happens. And I know this because I took economics, and I'd explain it to yea'... but I flunked that course. Not my fault. They taught it at 8 o'clock in the morning. And there is absolute nothing that you can learn out of one bloodshot eye. After I failed my second test, I grabbed my teacher by the front of the shirt and said 'Are you *trying* to keep this shit a secret?'"
