This was actually a pretty cute one.
Sheldon can't decide what he should change his specialty to. Penny suggests changing things up to get him out of his rut and help him decide. Leonard says they should reinstate "Anything Can Happen Thursdays." Penny, Leonard, and Sheldon go walking around to try and find a new restaurant, when they find Bernadette and Amy out for dinner. They had both made excuses as to why they couldn't hang out, so now they've been caught in a lie. They admit that they're tired of hearing Sheldon struggle with his decision, and tired of hearing Penny complain about her stupid gorilla movie. Even Leonard has to admit that Penny has been talking about it a lot.
Penny takes Sheldon and the two of them leave, both angry at their friends' lies. Leonard and Amy have a nice talk about Sheldon, and how hard it is to get close to him. Sometimes, Amy is jealous of the connection between Penny and Sheldon, even though it's obviously not romantic. Sheldon and Penny go to a psychic, which Sheldon obviously thinks is crazy. The psychic tells Sheldon that his life will get better if only he can full commit to the woman in his life.
