The Agreement Dissection

The code Sheldon uses to activate the "self destruct" sequence on his laptop, 1-1-A-2-B, is the code used by Spock in Patrouille du cosmos (1966): Let That Be Your Last Battlefield (1969). The layout of the program he is using for the countdown is similar to the designs of the computer screens seen first in Star Trek: The Next Generation (1987).

While at the bar with Penny, Amy and Bernadette, Sheldon is asked if he has ever kissed a woman. He states that other than family he hasn't, yet in 'The Maternal Congruence' he is kissed by Leonard's drunk mother. Given Sheldon's literal-mindedness he wasn't lying (or ignoring continuity), since he wasn't the one initiating this kiss. When asked, writer Bill Prady said that the kiss doesn't count since it was forced upon Sheldon. Also, since Beverly was drunk, they had all agreed at the time not to discuss it further for Leonard's sake.

CHUCK LORRE PRODUCTIONS, #341

Dear Concerned Viewers,

Thanks to the magic of computer graphics, the monkey in tonight's episode was not actually smoking a cigarette, nor was he ever exposed to secondhand smoke. At all times, every effort was made to make the monkey feel happy and safe. Nevertheless, he proved impossible to work with. During the week of production his behavior became increasingly erratic, to the point of refusing to come out of his trailer to rehearse. It wasn't until after we finished filming his scenes that we learned why. The monkey is a heroin addict. Yes, hard as it may be to believe, the monkey had a monkey on his back. Thankfully, an intervention was staged by the Geico lizard and he is now going through detox and a twelve step program at the Bonzo Center in Palm Springs. Everyone at The Big Bang Theory wishes him well.
