Howard & Bernadette: Key Episodes
The key moments from Howard and Bernadette's relationship including their first date, Howard's proposal, their wedding, and the births of their two children.
- The title references one of the lies that Sheldon and Amy "germinated" as part of their experiment in meme theory, that Amy was starting an herb garden.
Raj: Shut your ass!
Sheldon: I must say, Amy, pretending to have intercourse with you has given me a great deal of satisfaction.
Leonard: Did you hear about Howard and Bernadette?
Penny: Of course I heard about it, how did you hear about it?
Leonard: I heard it from Sheldon, he got it from Amy.
Penny: Damn it! I told Amy that in the strictest of confidence. Boy some people are such blabbermouths. Well whatever, I'm sure Bernadette can do better.
Leonard: Do you think a sexually ambivalent Indian astrophysicist with selected mutism and alcohol issues is better than a 100lb Jewish guy who lives with his mom?
Penny: You are kidding! Raj likes Bernadette?
Leonard: I didn't say Raj, who said Raj?
Penny: Okay give, how do you know? Did he tell you?
Penny: Well then who?
Leonard: I can't say
Penny: Priya told you, oh what a little gossip. Ya know, not an attractive quality in a woman Leonard. Not judging, just my opinion.
Leonard: Well the point is if this got out it would destroy Howard and Raj's friendship.
Penny: You don't have to worry, unlike Amy and Priya, I know how to keep a secret.
Leonard: You're the one who told Amy in the first place.
Penny: In confidence.
Howard: Oh great it's my cousin David about the ring. Hey David what'd you find? Sure half a carat is fine. Her freakishly small hands make anything look big. It's one of the reasons I love her.
Sheldon: If you don't mind, I'd like to stop listening to you and start talking.

While Sheldon and Amy attend a book tour by Brian Greene, Amy tells Sheldon of a piece of gossip she got from Penny: Bernadette is thinking of breaking up with Howard. Although Sheldon is initially disappointed that Amy is indulging in idle gossip, she convinces him that gossip is an aid to social bonding.
As Sheldon and Leonard play Wii Sports: Archery in their living room, Sheldon raises the topic of his discussion with Amy, passing the gossip on to Leonard. Leonard mentions the gossip to Priya, who reveals that Raj has a crush on Bernadette. When Leonard runs into Penny and tries to tell her the gossip, Penny is angry as she was the original source of the gossip and had told Amy not to tell anyone. Leonard informs Penny about Raj's crush on Bernadette, making Penny promise to keep it a secret. Meanwhile, Priya hints to Raj that Bernadette might soon be available.
In the university cafeteria, Howard reveals to the guys that he's about to propose to Bernadette. When Howard goes to discuss the engagement ring, the other guys are concerned that Howard might be setting himself up for heartbreak. Later, Sheldon and Amy are having tea in the apartment, discussing the news of Howard's proposal. Fascinated by how the news of Bernadette's rumored breakup spread within the group, Sheldon and Amy agree to test meme theory within their social circle. To begin their experiment, Amy tells Peny that she and Sheldon had sex and that she was thinking of starting an herb garden.
When Leonard brings home dinner, he tries to prompt Sheldon into talking about his supposed intimate encounter with Amy. After ascertaining Leonard was talking about their rumored sexual exploits and not a herb garden, Sheldon tells Amy via video chat that the rumor has started to spread. Later, Amy is surprised how quickly their news spread with the whole group finding out in less than twenty-four hours. While the gang eat dinner in the apartment, Howard proposes to Bernadette. Unexpectedly to everyone else, Bernadette accepts Howard's proposal.
Amy and Sheldon's experiment continues with the gossip that Amy is pregnant with Sheldon's child and she's thinking of getting orthotics.
