Storyline

It's approaching Christmas, and Leonard's mother is coming for a visit, something Leonard fails to tell Penny. Sheldon surmises it's because Beverly Hofstadter will not approve of Penny as a suitable mate for her son. Leonard has not even yet told Beverly that Penny is his girlfriend. Conversely, when Beverly arrives, Leonard finds out that Sheldon knows more about what's going on in her life than he does. When Leonard does find out news about the senior Hofstadter household, he becomes emotionally distraught as what he deems important news to him was previously withheld. But more importantly, Leonard sees this action as a further demonstration of the poor relationship he has with his family. Meanwhile, Penny believes she has a way for Beverly to be a bit more emotionally expressive. Written by Huggo

Quotes

[first lines]
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 ...

Best Christmas Theme Episode of BBT

Review Date 6/24/2019

I have Reviewed OVER 500 "Christmas Films and Specials". Please BEWARE Of films and specials with just one review! For instance When "It's a POSITIVE" chances are that the reviewer was involved with the production. "If its Negative" then they may have a grudge against the film for whatever reason. I am fare about these films.

It's Christmas time and Leonard mom comes to visit. Lots a huge laughs in this episode. Look at the final moment and it looks like Jim and Christine they unintentionally hit their heads pretty hard .
