Amy and Sheldon plan a trip to the wine country with Howard and Bernadette on The Big Bang Theory. "The Locomotive Manipulation" is the 14th episode of the show's seventh season.
Leonard: Plus, I'm not sure it's a great idea to take Penny to where wine comes from. [chuckles] What? It's a joke. Oh, come on. We bust on each other. I wear dorky glasses, you might have a problem -- it's all for laughs. Penny: That would really piss me off if I didn't have a buzz going on.
Amy: I'm sorry, but "Gollum" and "Flakey" are not acceptable. Sheldon: Well, you don't like "Princess Corncob," you don't like "Fester" -- you're just impossible to please.
