Review of The Cooper-Hofstadter Polarization

While Sheldon, Leonard, Howard, and Raj are being awestruck at the way they've used the internet to communicate with the world in order to turn on the lamp, stereo, and other electrical appliances, Leonard discovers a letter inviting him and Sheldon to share their scientific knowledge to an audience of fellow colleagues. Sheldon threw it away because he doesn't feel the need to share while Leonard decides to go and has Penny help with the wardrobe. Penny tries to patch things up with the two former buddies but inadvertently makes things worse. So with her, Howard, and Raj in the audience, Leonard presents his theories to a crowd of 25 before Sheldon reveals himself among them as they get into a knock-down fight in front of everyone. Suffice it to say, Howard sent his cell-phone version to YouTube which also accepted his same-place filming of him and a sleepy Penny with the caption of "his girlfriend". We find out later that a couple of nerds in China have seen this and are also awestruck at their lamps turning on and off at will...With the strike finally over (congrats to the writers for getting much of what they deserve), CBS presented an all-new Monday comedy lineup starting with this one in the middle of March. With this episode, "The Big Bang Theory" comes back funnier than ever! Loved the references to Scanners whenever Sheldon tries to "blow" up Leonard's head. There's also a running joke told by Leonard that only Penny doesn't get. And how about those clothes Penny tries to discard or the model city of Kandor she discovers. All I can say is, bravo to CBS for renewing this very entertaining show for a second season. Oh, and loved Chuck Lorre's reference to producing two shows competing with a "deaf diva dancing her (behind) off" on his vanity card at the close!
