Everybody knows retards are stronger than normal people. Its that retard power that acts like a super adrenaline in their muscular tissue. I've seen retards smash through walls when they thought a pretty shiny thing was on the other side. I mean just look at Dr. Bruce Banner. When he becomes the unstopable force of the Incredible Hulk, all he can say is "Hulk smash!".

Just need to give the retard the proper mental stimulus, like say any movie with Freddie Prinze Jr. in it. And as they start to flex and get jittery in their seats, the retard energy builds up in their muscles, and just funnel the energy from the cushions. Or you could announce a sale at the Gap, everything purple half off, and pump the retard energy from the clothes racks. Or transmit the retard energy from the vans of Phish fans that follow the band from venue to venue. The possibilities are endless. Retards could be the answer to our conservation woes.
