Extended Plot

Shamy plot: Sheldon and Amy begin to collaborate on a scientific project when Sheldon realizes something she's been working on could have implications with regard to a challenging issue in quantum mechanics. They try to work out some ground rules between them for this new kind of interaction and find that being snarky with one another helps their cognitive thought processes.

Other plot: Raj and Penny get along so well doing various "girly" activities together that Leonard feels left out. He spends some time with Howard and Bernadette before bringing it up to Raj and Penny.
