[Leonard is taking Sheldon's MVPD to work in their car]
Sheldon: I don't understand why you're not enjoying this. Together, in this car, with my enhanced capabilities, we're like Knight Rider.
Leonard: Except, in Knight Rider, the car isn't a yammering sphincter.
Sheldon: You mock the sphincter, but the sphincter is a class of muscle without which human beings couldn't survive. [an image of internal human body anatomy with numerous arrows appears on the MVPD's screen] There are over 50 different sphincters in the human body. How many can you name?
Leonard: I was wrong. This is exactly like Knight Rider.
