Raj tells her how he went to, which reminded him of , where in fell in love with astronomy. "Raj is my name and stars are my game. And rhyming is also my game." He then ask about her, but first she excuses herself to the restroom. Raj thinks that everything is going great until we see Lucy passing the front window leaving him alone.

The next day, Sheldon is taping a Fun with Flags episode in his apartment. He apologizes for not airing an episode last week because Leonard pointed out that when he dressed up as for  that show was racist. Penny is Sheldon's guest and is described as a flag virgin, but not a real virgin since she has had coitus. Penny joins him and says that she has many times been at a party and has not been able to join in the discussions about flags. Penny stops the taping and shows him how to loosen up using things she learned in acting class like talking to his guest and not to the camera. Also he should have his arms opened instead of crossed thus welcoming everybody in. Sheldon mentions that he has gotten comments about his robotic delivery and that must not be a compliment. Sheldon then looks too relax almost like he and Penny are a couple. Penny then says that she is from Nebraska so Sheldon shows her and describes the Nebraska state flag now sitting stiffly. Following on Penny's earlier comments, he tells her to spread her legs and invite everyone in.

Howard, Bernadette, and Leonard go to visit Raj after not hearing from him for a few days. Howard says taht he can always feel when Raj is in trouble.

Inside they find Raj moping over Lucy looking terrible and his apartment a wreck. Raj tells them that he was humiliated by yet another woman. Howard asks him if he chopped her up and that that was what they were smelling. Raj explains that he took her to coffee and that she left and climbed out a very tiny window in the bathroom meaning that she was highly motivated to leave. The guys tell him that he has to shake himself out ,however he claims that he is never going to leave his apartment especially since he can order anything from Amazon including lobster. Howard and Leonard find this point interesting since they could put together an order of Surf and Turf. Bernadette wakes them up since they want to get Raj out and not get them settled in. Raj tells them to leave him along and goes into the bedroom. As they leave Bernadette has a yen to go to saying at least she waited on her lobster craving until he left.

At the comic book store, Sheldon mentions how he hasn't seen Raj lately and if he is now out of their social group, Sheldon want to add a Latin person. Howard tells Sheldon that Raj has decided to never leave his apartment again. Sheldon thinks that that idea is brilliant. Lucy enters the comic book store and approaches Stuart.

She says that she is sorry and asks him to give him a note. Howard replies that Raj is a proud man and that if she walks out again, she is only going to have five or six more chances.

Howard is sitting in Raj apartment and he is now dressed in only and a  eating. Howard tells him that he should celebrate and call her. Raj doesn't want to call her and replies that he is going to be a monk, renounce all worldly pleasures except eating lobster. Raj tells Howard that he is a good friend, but Raj has made his choice. Howard leaves with Lucy's note. After Howard leaves, Raj runs down the street in his underwear to get the phone number back from Howard.

She doesn't even like comic books. Raj first agreed with her and then said that he did like them. Lucy said that is kind of broken and then Raj told her that he was too. She said he wasn't. Raj then admitted that he couldn't talk to her without his beer and that he has major psychological problems.
