Plot

Sheldon tries to relax after he is forced to take a vacation. Leonard struggles to be supportive of Penny after she quits her job. Amy receives unwanted attention from a co-worker. Bernadette seeks Stuart's help in replacing one of Howard's comic books.

Following her recent acting disappointment, Penny decides she needs to take decisive action to make her career happen by devoting her time one hundred percent into the endeavor, which means quitting her waitressing job. Although he wants to support Penny outwardly in whatever she decides, Leonard does not support this move. He has to decide whether he will tell her the truth or lie about his feelings. Sheldon, who is affected by the goings-on between Leonard and Penny, is however more perturbed by a mandatory request by the college: that he take his vacation time. Meanwhile, Amy, with a little help from Howard and Raj, comes to the realization that one of her colleagues, Bert from the Geology Department, has a crush on her. Regardless of her dating status, she isn't interested in Bert, but she doesn't know how to show or tell him that she's not interested without hurting his feelings. And Bernadette is trying to find a replacement for a rare comic book of Howard's that she accidentally ruined. As Stuart doesn't have a copy of it at his store, she has to decide whether to be loyal to Stuart, or to buy the one available copy in town from Stuart's much hated rival, Jesse.—Huggo

Walking up the stairs, Sheldon complains to Leonard about how the university is forcing him to again take a vacation. Leonard is worried about his relationship with Penny after he panicked when she marriage proposed while frustrated and tipsy. Leonard goes to Penny, Penny comes to the door, apologizes for not texting him back and invites Leonard in. Penny assures Leonard that she doesn't want to break up with him. Leonard is willing to support anything she wants to do. Since acting is Penny's real dream, she wants to focus entirely on it, so she quit her job at the Cheesecake Factory.

The next day Leonard is heading to work and Sheldon is begging to go with him. Chasing Leonard down the stairs, Leonard shouts at him to "stay" on the stairs one flight down and tells him to not follow him. Sheldon sits down the stairs whimpering like a puppy.

Stuart sighs behind the counter in an empty comic book store. Bernadette comes in to replace a comic of Howard's that she accidentally ruined. She tells Stuart that Batman got his ass whipped by a curling iron. Bernie needs the replacement quickly as she doesn't want Howard to find that she messed up.

Amy is in her lab at Caltech looking over a rat's brain under a microscope. Raj and Howard wander in asking her if she'd like to join them for lunch. Bert (Brian Posehn), a big guy from the geology department enters, and Amy introduces him. He gives Amy a piece of black quartz. Bert leaves with Amy describing him as nice. She is surprised when Howard explains that he likes Amy. In their conversations, the subject of Sheldon being her boyfriend has never come up.

Penny leaves her apartment with a box full of photos and resumes and finds Sheldon still sitting on the steps. He complains about being forced on vacation and that Leonard has told him to stay. As she is leaving Sheldon whimpers again and she invites him to come along by calling him like a dog.

Back at the comic book store, Stuart finds a copy for Bernadette at Capitol Comics Store, a rival to his store whose owner Jesse (Josh Peck) is a successful jerk. Stuart offers to take her there so she won't get ripped off.

Amy is having lunch with Leonard, Howard and Raj. She is surprised that Penny quit her waitress job. Leonard says that he supports her decisions, though is obviously nervous about it. He calls up Penny who says that she is at the Cheesecake Factory. Leonard quickly replies that he is so glad she went and got her job back. Unfortunately the peeved Penny was just turning in her uniform. He finishes that he still supports her decisions.

Sheldon is waiting for Penny in her car. Penny wonders if quitting her job was a mistake since it really bothered Leonard. Penny does not know why Leonard can't understand it. Sheldon concludes that the two of them are a lot alike; they are both dreamers.

Bert returns to Amy's lab and asks him to accompany her to a rock and mineral show. Amy mentions that she already has a boyfriend which makes it awkward for Bert. Bert thinks she is turning him down because he has an off-putting personality. Amy breaks down and agrees to go with him. Her comment makes him very happy as he says "Sweet; it's a date," and leaves. Amy says that it is not a date. Down the hallway Bert says that it's too late.

At Capital Comics, Bernadette is impressed how crowded the store was. The owner greets Stuart and tells him how gray his skin has gotten. He goes to get Bernadette the comic. He offers Bernadette a latte and Stuart the directions to the nearest soup kitchen, which isn't necessary as Stuart already knows the location. Bernadette doesn't like how he is treating Stuart so she leaves to get the comic elsewhere.

Howard and Raj are now commiserating with Amy over her date with Bert. According to Howard, going to a rock show would be terrible even without Bert. Amy wonders what to do and Raj tells her to prepare her uterus for a very large offspring. Amy plans on being brutally honest with Bert; however, Raj thinks that that might send him up the Empire State Building and start swatting at passing airplanes. Finally Howard and Raj offer to talk to him and let him down gently. Going out the door they both agree to tell Bert that Amy is a lesbian.

In Apartment 4A, Penny and Sheldon are doing yoga. After Leonard asks, it seems that Sheldon is doing yoga because he thought Penny had said Yoda, the Jedi master. They start to discuss his phone call. Leonard would have discussed it with her before he would quit his job. They start to discuss the kind of relationship they are in as Sheldon then joins them. He feels that he is in the relationship as much as them. He wants to know when they are getting married and where all of them are going to live. Finally Leonard tells her that he is on her side and that he would never have courage she exhibits quitting her job to follow her dream.

Bernadette angrily walks back into Capital Comics telling the owner crossly in her "Mrs. Wolowitz" voice that Stuart and his store are just fine, Stuart is a much nicer person and that she still wants to buy that comic. And have a cappuccino and a blueberry scone.

Finally Raj and Howard end up going to the mineral and rock show with Bert in lieu of Amy. They are in his dilapidated car going down the highway as he keeps shouting "Rock show!" and they look very unhappy.
