What not?

They're getting fatter and stupider you know. They're getting fatter and stupider by the minute. They breath and enervate. They breathe and eat the fat which clogs the brain. My, how they grow: guts stealing mass from brain.

Soon we won't be able to grow, you know. We'll have taken all the space up. Soon we won't be able to go any further than our doors, lest we walk through another's doors. Each half an ounce of mass in the brain is equivalent to limitless activity, yet only makes fifty pounds of fat and flesh. We'll be big we will! We'll fill in our door frames, expand our tubs we will, we'll will our influence on the bruised universe.
