TEXT: Scene: Outside an apartment building. Howard: So two years later, there's a knock on the door, guy opens it, and there on his porch is the snail, who says, "What the heck was all that about?" Bernadette: I don't really get it. Howard: Well, see, it took two years for the snail to... (she kisses him) not important. Bernadette: Can I ask you a question? Howard: Sure. Bernadette: Where do you think this is going? Howard: To be honest, I was hoping at least second base. Bernadette: You're so funny. You're like a stand-up comedian. Howard: A Jewish stand-up comedian, that'd be new. Bernadette: Actually, I think a lot of them are Jewish. Howard: No, I was just... never mind. Bernadette: Look, Howard, this is our third date and we both know what that means. Howard: We do? Bernadette: s*x. Howard: You're kidding. Bernadette: But I need to know whether you're looking for a relationship or a one-night stand. Howard: Okay, just to be clear, there's only one correct answer, right? It's not like chicken or fish on an airplane? Bernadette: Maybe you need to think about it a little. Howard: You know, it's not unheard of for a one-night stand to turn into a relationship. Bernadette: Call me when you figure it out. Howard: Three dates means s*x? Who knew? Scene: The apartment. Howard: Greetings, homies, homette. Penny: Why are you back from your date so early? Howard: In romance, as in show business, always leave them wanting more. Penny: What exactly does that mean? Leonard: He struck out. Credits sequence. Scene: The university cafeteria. Howard: Hey, did either of you guys know that three dates with the same woman is the threshold for s*x? Raj: Actually, I've never had three dates with the same woman. Leonard: With Penny and me, it took two years. Now that
SUMMARY:
After three successful dates, Howard reflects on the future of his relationship with Bernadette. He surprises her with a last-minute proposal, which she declines as it is much too soon for either of them. However, he wins her over by performing a cheesy love song, which she finds as romantic. A prank fight between Sheldon and Kripke begins when the latter severely embarrasses the former on National Public Radio's talk show Science Friday by filling Sheldon's office with helium, giving him a high-pitched voice. It ends with Sheldon dropping foam from the ceiling into Kripke's office, but accidentally does it when President Siebert and the Board of Directors are there to see Kripke's progress on one of his experiments. Afterwards, a pre-recorded message from Sheldon plays from Kripke's computer, explaining that Sheldon was responsible and that Leonard and Raj were involved.
