1.)Hey Jim, this stereo set up is fucked. I'm pumping out 200W but my system sounds like a transistor radio. That is one fucked up signal-to-noise ratio.

2.)Typically, a demogague actually benefits from non-sensical, contradictory and inflammatory statements and agendas. Ironically, the higher the signal-to-noise ratio, the more effective they become since any useful information would actually reign them in.
