Cave Johnson here,

after sending out Aperture's PeTI, Perpetual Testing Initiative, we received a whole mass of blueprints. Most of them were pretty much err... sugar! But still there are almost respectable results and we actually are saving money! Plus we don't even have to spend money for toilet paper anymore.

Many average plans have already been implemented and every passing day there are more. This time we introduce designer six, five, seven, nine, seven, eight, o, eight's modelling. These chambers ain't good, but they reach the bare minimum expectations. In fact not much better than a monkey could do. But we could hire him as employee and we pay him only one dollar and a banana per chamber. So at least we gained another new and cheap test subject.
