Last night pretty much marked the first episode that Leonard and Penny were a full-fledged working couple.  The two of them have apparently worked out their sexual issues from the last episode and are now having a bed-breaking good time.

However, now that Penny is spending a lot of time around the apartment, Sheldon has to come up with a new approach to deal with her... conditioning her using positive reinforcement.  Meanwhile, Raj and Wolowitz head to a local goth club in order to pick up chick.

Find out how our favorite nerds did in their respective missions in our recap of "The Gothowitz Deviation."

Now for some of the best of The Big Bang Theory quotes of the episode:

Wolowitz: They're called tattoo sleeves. I bought them online. Raj got a set too. Put them on, have sex with some freaky girl with her business pierced and I can take them off and still be buried in a Jewish cemetery

Penny: I give up, he's impossible
Sheldon: I can't be impossible, I exist. I believe what you meant to say is, "I give up, he's improbable." | permalink

Sheldon: Interesting. Sex works even better than chocolate to modify behavior. I wonder if anyone else has stumbled onto that
