"Welcome to the Aperture Science Enrichment Center. Let's look at some of the challenges you will face as a test participant. You may be required to perform simple tasks such as locating an exit. These simple tasks may be supplemented with insurmountable obstacles. Thanks to the Aperture Science Handheld Portal Device, the impossible, is easy."
