Trivia

 * First ever in the series, this episode shows a scene that in a video game, all the players are female characters (Penny and Amy). They are playing skiing game in on the Limited Edition Kinect Star Wars Bundle of  that previously appears in The Extract Obliteration (S6E06) and The Contractual Obligation Implementation (S6E18).
 * This is the first appearance of Mrs. Wolowitz's bedroom.
 * This episode was filmed on two separate days, and the audience included people who were touring WB Studios like "The Scavenger Vortex" which had many short scenes in it.
 * The scene that Howard turns his mother around to reveal that she is dead and a skeleton (in Howard's imagination) is an obvious reference to 's classic thriller.
 * This is the first episode since "The Engagement Reaction" (S4E23) in which Bernadette is shown working at The Cheesecake Factory, although this was only her imagination.
 * In Leonard's imagination about what if Penny ended up with Zack, instead of paying rents, Zack use the money to buy magic beans. This might be a humorous reference to "The Precious Fragmentation" (S3E17), in which instead of buying lunch, the gang bought a box of stuff from the garage sale, to which Penny mocked "you didn't trade the food for magic beans, did you?"
 * The Sheldon-Penny scene is a tip of the hat to the Shenny [Sheldon and Penny should be together] fans, despite it is only a scene out of Amy's imagination.
 * Penny offered to Sheldon to have sex in the laundry room with her, though she wouldn't do it with Leonard in "The Stag Convergence". Though it was only a fantasy of Amy's.
 * Sheldon doesn't mention that in the last episode Missy appeared in, he spoke of her offspring being potentially another Sheldon-like genius since they have the same DNA heritage. Here she has her first baby.
 * The audience again gets to see Mrs. Wolowitz, or at least her body.
 * This episode marks the return of Mary Cooper after being absent from season 6, although we only hear her voice.
 * Raj sat in Sheldon's spot for much of the episode while Sheldon was out of town.
 * This is the second episode where Sheldon expresses dissatisfaction of menial work in regards to his talents. The first was "The Vacation Solution".

Critics

 * Jesse Schedeen for IGN - Without Sheldon, the Big Bang Theory probably wouldn't have been very successful. And that idea was sort of at the heart of this week's holiday-themed episode. Taking a little inspiration from It's a Wonderful Life, the rest of the gang wondered how their lives might have played out if Sheldon weren't around. Would they still big a tight-knit unit?...But again, what we were given was entertaining enough. It was amusing to see the course each character's life took without Sheldon as a guiding influence...This was a perfectly decent holiday episode to cap off 2013. It offered fun glimpses of a world without Sheldon Cooper (as well as one where Penny had the hots for Sheldon), and it gave Amy the happy ending she deserved.
 * Dhruv Rao of The DR Club gave the episode a B.
