1. Mindless reality shows such as Hole in the Wall contribute mightily to the retardification of the citizens of the United States.
2. If one watches more than 2 minutes of Mind of Mencia, they automatically lose 15 IQ points, as proven in studies conducted by an institute. That makes Mind of Mencia one of the world's leaders in aiding the retardification of the Earth's population.
