The Big Bang Theory

The Locomotive Manipulation

Series 7 - Episode 15 The Locomotive Manipulation



Poor Amy. The romantic longing she feels for her boyfriend is all too easy to see on her permanently dejected face. But this is Sheldon Cooper we’re talking about. Excitement for him is a neat scientific equation, a rare Star Wars figurine or, as is the case here, the chance to ride aboard an Alcoa FA-4 diesel locomotive.

But Amy (the show’s unsung heroine, Mayim Bailik) and those who’ve suffered along with her are about to be rewarded… eventually. And yes, there’s applause. It’s all heart-flutteringly sweet, unlike Raj’s nauseating attachment to Cinnamon, his Yorkshire terrier. Bleurgh! This episode'saward for best line delivery goes to Sheldon (who else?) for: “I hate every word in that sentence.”


Sheldon and Amy take a train ride to the Napa Valley with Howard and Bernadette on Valentine's Day, while Leonard and Penny head to the vets when they volunteer to look after Raj's dog. Comedy, starring Johnny Galecki, Jim Parsons and Kaley Cuoco.
