This is also Amy's only Valentine's Day gift.

Howard and Bernadette get ready to use their new hot tub. Bernadette wants him to check the temperature to make sure it's not too hot. Howard thinks he sees a rat floating around in the tub. He goes for a kitchen strainer while Bernadette turns off the hot tub jets.

Leonard and Penny are waiting for their table; however, there is a wait of an hour even though they had a reservation. Leonard thanked him in a bad-ass fashion. Penny suggests that he slip the host (Creagan Dow) some money. Leonard goes over to again check on their table and he drops a twenty dollar bill on the floor. Leonard asks the host if it was his and the guy announces to the room whether someone lost a twenty. A customer next to him claims it.

After announcing the new title of the show, Amy offers to take any flag related questions or comments. To answer some initial questions. Yes, he is a real doctor. And yes, Amy is his girlfriend. Amy says that she just blinks a lot and is not sending out "rescue me" in Morse code. Their first call is from Raj who wants to know what is wrong with him and why he was so self-destructive. Amy attributes it to good communication. Sheldon wants to cut him off and take a flag question.

Howard tells Bernadette how much he loves her as she rescues the animal. It's a rabbit that is alive, but unconscious. He was to be kept warm, but then he was in a hot tub. If dehydrated, give him some fluid with electrolytes, and wash down his face and genitals.

Penny is getting tired of waiting and decides to flirt with the host. Penny starts to get friendly, but he claims that there is nothing he can do, "ma'am". Penny jokes that he doesn't have to call her ma'am since they are the same age. He disagrees since he is twenty-one. Penny makes Leonard leave while she's still young.

Still talking to Raj, Amy explains that it is common to have doubts after a breakup. Sheldon wants to give out flag facts. Sheldon tries to help but still comes back to flag facts. Another call comes in and it's Barry Kripke who wants to talk about how lonely he is. He's looking for a young slim Asian woman. Kripke asks if his pole is a flag related topic.

Howard and Bernadette have the rabbit taking some fluids and are very happy they are working together. They decide to name him Valentino Wolowitz Rabbit. Howard plays with him and then gets bitten. Howard is worried about getting rabies.

Leonard and Penny are now eating fast food in the car. Leonard is worried whether it was a good substitute and Penny calls it freaking amazing. She was both hungry and cranky about getting called ma'am. Penny complains that when they met she was only 22. Penny then reminds him that he is almost out of his thirties. They decide they want to do something to make them feel young. Leonard tries to start a food fight and Penny just stares at him.

Amy continues to give the guys advice as Sheldon gets more and more disgusted. When Belize became an independent country, they created a flag with a tree on it. Sheldon wants to hang himself from it. Kripke insults Amy, so she cuts him off. Amy then asks the viewers for any interested ladies to call in if they want to meet Rajesh. Another call comes in, but it Is just Kripke who wants to know how many men she has had sex with.

Penny is looking up fun things to do like dancing. Skinny dipping at the beach. A sing-along "Moulin Rouge" movie is playing. Then Penny finds out that it is sold out; however, both are happy about that.

Howard finds out that rabies in rabbits is highly unlikely. Bernadette suggests that they take him to the vet and have him tested. Unfortunately the rabbit has to be killed and have his brain checked. Howard wants to go to the emergency room just to be safe. Howard leaves as Bernadette says to Valentino, "We'll find another time to tell him I'm pregnant."

Sheldon now has his head in his lap while Raj goes on. Then he decides that this is no longer fun so he erases the word on the white board behind him. It's no longer about flags so he erases that. And Sheldon hasn't been talking so he erases his name. The new Internet show is "Dr. Amy Farrah Fowler presents with". Sheldon then gets dragged in and tells Raj that pain is part of the evolutionary process that provides information from the environment that that behavior isn't good for one. Also, Sheldon admitted that when they broke up he suffered, but was glad that they did break up since they are a much stronger couple now. During Sheldon's confession, Leonard and Penny burst in dressed as cupids, wishing everyone "Happy Valentine's Day" and throwing confetti around trying to feel young.

Finally, Sheldon and Amy are toasting a successful live "Fun with Flags" show and a lovely Valentine's Day. Penny and Leonard are cleaning up the confetti which Penny does not consider to be young and fun.
