A Quote from Portal 1
GLaDOS
We are pleased that you made it through the final challenge where we pretended we were going to murder you. We are very very happy for your success. We are throwing a party in honor of your tremendous success. Place the device on the ground, then lie on your stomach with your arms at your sides. A party associate will arrive shortly to collect you for your party. Make no further attempt to leave the testing area. Assume the Party Escort Submission Position, or you will miss the party.
