The rule on the denkoitus in the roommate contract was definitely addressed to Leonard, since Sheldon only participated in this kind of activity for years (and years…). Sheldon: If Leonard doesn`t sign the new agreement in the next 41 seconds, this computer will send an email to your parents in India to say you`re in secret contact with the whiter than The Marshmallow-Fluff Leonard Hofstadter. Sheldon: Oh, well, you`re upstairs. I have written a new roommate agreement which is very useful to me. I want you to sign it. Sheldon: Great question. Remember what happened with the alien played by the talented character Frank Gorshin in the Episode Star Trek Let That Be Your Last Battlefield? Sheldon, who has taken his love for rules and guidelines to the extreme, has created an epic agreement of roommates that Leonard must approve to live there. Although Leonard did not always accept the agreement, he tried to save Sheldon`s face so as not to upset him. Nevertheless, it was only 10 of the rules of Leonardo`s roommate`s agreement that brought all the sneers to the show. I think this episode was not only the funniest of the series (so far), but the best written/executed. I watch it over and over again when it`s re-mattered. If you saw the episodes that led to “this” one after the other, you would have recognized the “Lead Ins” on the jokes (i.e. Amy`s previous mention that she was working with monkey and lung disease).
The scenes intertwine perfectly, and while there are two main threads (scenes with Leonard and Pria and the one with Sheldon and Amy), they combine at the end for the hilarious finale (although only Sheldon is in both parts of the final scenes and glues them together). The character Sheldon and Amy always play “straight” and serious, although the results are the funniest of the episode. And, you have to believe that “not all” parts with the monkey are CGI… But even if Sheldon and Amy wanted a turtle, he`d be breaking his own rule. In the roommate agreement, he explained that pets were in fact prohibited, unless they were pets! The roommate agreement was written by Sheldon and signed by Leonard when they became roommates for the first time. These events were reported during a flash-return. Sheldon begins to mention in the episode “The Cooper-Nowitzki Theorem” paragraphs of a friendship treatise. Subsequent episodes describe him as a roommate agreement, and Sheldon continues to quote him throughout the series, usually when one of the clauses is violated.
According to the roommate`s agreement, Sheldon insists on having different types of foods different on weeknights.
