The Big Bang Theory: ‘The Maternal Congruence’ Preview

Acting veteran Christine Baranski, currently a star of CBS’ hit rookie drama The Good Wife, reprises her role as Leonard’s mother Beverly on the new December 14 episode of The Big Bang Theory called “The Maternal Congruence.”

And Beverly is one powerful parent indeed.

While her visit makes Sheldon insanely happy, it also mortifies her poor son.

Check out a sneak peek and short promo for “The Maternal Congruence” below. The second video shows exactly why Sheldon loves his roommate’s mom so much. Yikes!

The Big Bang Theory airs Mondays on CBS at 9:30pm ET.
