Notes and Trivia
- Bill Prady revealed on his Twitter account that Danica McKellar, star of The Wonder Years and author of best selling mathematics books, would guest star in the 11th episode of this season. The episode aired 12th, however, since Maternal Congruence was shown out of order on 14 December as the 11th episode of the third season.
- Sheldon's move to let Martha stay in his bedroom at the end of this episode is rather surprising considering his strict "people can't be in my bedroom" rule that he has highlighted many times (e.g. 0203, 0217).
- The "Green Lantern lantern" which Sheldon carries isn't really called that. The correct name is Green Lantern Power Battery, which Sheldon would certainly have known.
This episode takes place over several days presumably early January 2010.
