When Sheldon gets in the way of something, even his trusted friends would do anything to stop him, this is the time when Leonard and Howard team up to do that. Although the plan will still be as hilarious and wholesome for the show, their goal is to trick Sheldon to do their invention by praising him for being the best engineer. In turn, the usually naïve Sheldon will do the running locomotive and help Leonard and Howard finish their invention through his friend's motivation.

On the next new episode of the "Big Bang Theory" Season 10 titled "The Locomotion Reverberation", Sheldon had been delaying the invention Leonard and Howard are doing. However, in the course of their work, a problem came for them to stop working on the invention, or this may be another of Leonard and Howard's plot to put Sheldon out of the project. Based on reports from SpoilersGuide, Leonard and Howard made up a plan to divert Sheldon's attention and even kick him out of their collaboration.
