Montage of Mr. Johnson’s best quotes about what science can/will/has done to you.
Now if you have yet to play the awesomeness that is Portal 2, you may or may not want to watch. It only shows pictures of Cave Johnson that can be found in the game and the audio only gives you trace amounts of data about the levels you may encounter. Spoiler level is around 2%. You probably drink milk that’s that bad. You probably saw more spoilers in the trailers! So quit your whining and let us science you up, dang it!
