The episode is called An Academic Crime and a More Romantic Taco Bell, and it airs at 9pm ET. It features Sheldon accusing Dr Sturgis of plagiarism.
Fans are interested in the cast of this show, particularly Sheldon’s father – who is played by Lance Barber. This actor plays George Cooper Sr.
In fact, Barber was in an episode of The Big Bang Theory, but played a different role – that of Leondard’s childhood bully who came to visit him.
