Continuity: At the bar, when Penny tells Beverly she's sleeping with Leonard, the position of Beverly's hand on her shot glass and the amount of liquid in it changes between shots.See more »

Penny:Ah, I always tear up when the Grinch's heart grows three sizes.
Sheldon Cooper:Tears seem appropriate. Enlargement of the heart muscle, or hypertrophic cardiomyopathy, is a serious disease which could lead to congestive heart failure.
Leonard Hofstadter:[to Deck the Halls] Fa-la-la, la-la-la, la-la-la.
Penny:You really didn't like it, Sheldon?
Sheldon Cooper:No, on the contrary. I found the Grinch to be a relatable, engaging character. And I was really with him right up to the point that he succumbed to social convention and returned the presents and saved Christmas. What a buzzkill that was.

"The Maternal Congruence" was an excellent holiday episode of "The Big Bang Theory", 28 January 2011
Author: tavm from Baton Rouge, La.

*** This review may contain spoilers ***

After Penny and Leonard watch "How the Grinch Stole Christmas" during which Sheldon comments how he felt compatible with the leading character...until he gave the presents back, Sheldon casually mentions Leonard's mother is coming. Tomorrow. Penny is aghast since she didn't know about it and becomes more so when Sheldon also mentions that her boyfriend's mom doesn't know about his relationship with Penny. Actually, Beverly and Sheldon have been e-mailing each other about stuff her son Leonard doesn't know like her surgery, her divorce, and their dog's death...This was another hilarious ep of "The Big Bang Theory" with Christine Baranski's return as Leonard's mom a big treat here. Her delivery with the lines are just sublime here especially when she and Penny have a few drinks. Oh, and just try to keep a straight face when she discusses with Howard his "relationship" with Raj! So on that note, "The Maternal Congruence" was another excellent episode of "The Big Bang Theory".
