时长:00:21:30 / 首播:2015-12-10
Sheldon is humming the melody of a song that he doesn't know the name of, especially unusual because of his Eidetic memory. He spends two days obsessing over the tune and recording himself while he is still mentally sound, fearing he might be turning into a mad genius, annoying Leonard and Penny. Sheldon finally realizes the song is Darlin' (The Beach Boys song), and that the lyrics relate to how Amy made him a better man. He rushes to her apartment.

Amy calls Dave for another date at her place, though Bernadette cautions that could lead to intimacy. Although Dave brings up Sheldon again, the date goes well and they kiss once as Sheldon arrives to profess his feelings. With Dave's help Amy realizes Sheldon loves her and wants to get back together. She agrees and they kiss passionately, twice, and kick Dave out of her apartment.

Meanwhile Howard and Raj's fan page for their filk band is liked by one person named Trent. They stalk Trent online and think he is very cool and decide to go meet him, only to run out when they see Trent pick his nose and eat a booger.

Recurring character: Stephen Merchant as Dave Gibbs
