Episode complete credited cast:


When Leslie Winkle asks Leonard to join the faculty string quartet, he has no idea that it may lead to more personal endeavors, especially as their first and only experience in dating each other went nowhere. Leonard's not sure how to reconcile his feelings for immediate sex with Leslie versus his want to date Penny, especially if Penny finds out that he is in a potential relationship. Sheldon's not sure what the protocol is when a roommate has a spontaneous "guest". But Sheldon is aware that by the end of Leonard and Leslie's encounter, he feels violated. And Leonard's feelings may change when he understands Leslie's motivations. Written by Huggo

[first lines]
Sheldon Cooper: Alright. I'm moving my infantry division, augmented by a battalion of orcs from Lord of the Rings. We fight the Tennessee Volunteers, and the North once again wins the Battle of Gettysburg.
Howard Wolowitz: Not so fast. Remember the South still has two infantry divisions, plus Superman and Godzilla.
Leonard Hofstadter: No, no, no no. Orcs are magic; Superman is vulnerable to magic. Not to mention, you already lost Godzilla to the Illinois Cavalry and Hulk.

Crazy Credits

CHUCK LORRE PRODUCTIONS, #189 Last winter the magazine Entertainment Weekly did a story about me in which I was called "the angriest man in television." When the article came out I shrugged and said things like, "Oh, it's just a trashy tabloid, it doesn't mean anything." But you know what? That's a lot of crap. It's taken me ten months to get in touch with my feelings about that article (pretty quick for a guy), and guess what? I'm angry! How dare anyone suggest I have no right to feel what I feel? If you're even barely engaged in this world, anger manifests itself constantly (assuming you're not medicated, which I am not, dammit to hell!). And let's be totally honest here, anger does a lot of good. It clenches my stomach muscles into a tight knot so I can look good with my shirt tucked in. It adds hours and hours of productivity by keeping me awake until five o'clock in the morning. It's a constant reminder that I should never own a gun. It makes golf an opportunity to practice my javelin toss. It fills me with joy every time Lewis Black is on The Daily Show. It adds sizzle to caffeine. It whispers to me that I'm fine, that I don't need to slow down, and that my cardiologist is an idiot. It keeps people at a healthy distance during flu season (and the rest of the year as well). And finally, it encourages me to use my vanity card to foolishly burn bridges with TV critics. Hey EW! Do not screw with me. I've got two vanity cards now, and I'm not afraid to use 'em Okay, the sun's coming up, I'm gonna try and get some sleep. See more »

Fifth episode of "The Big Bang Theory" is another funny outing
22 October 2007 | by (Baton Rouge, La.) – See all my reviews

Leonard, Sheldon, and their two friends are at Penny's restaurant playing a game that mixes Civil War generals with various sci-fi heroes. Penny tells them they have to order something or they'll get thrown out. Leslie, Leonard's lab partner, comes by and asks if he'll agree to play cello for her music group. He agrees. Once there, Leslie has to make obvious what her intentions are so Leonard doesn't get confused. Meanwhile, Sheldon asks Penny over to his place in order to get her to tell him what the tie on Leonard's door with music playing inside means. With Penny now knowing about Leonard and Leslie, Leonard makes his move on Leslie but she tells him she won't be available to him "until at least New Year's". So a relationship is over before it really began...Another funny episode of "The Big Bang Theory" with the welcome return of Sara Gilbert as Leslie. Many funny double-entendres abound. Most of the best lines, as usual, come from Sheldon. Glad to know this show is doing well for the CBS Monday lineup. Will post another review next week...
