Sheldon makes the excuse that he has company (his other two selves). After some deliberation, he lets Raj in who tells him he has received a new drug his friend claims to be "" for people with. Raj is worried that the s will affect his brain, which is a very important tool in his field. Sheldon reassures him as he believes Raj isn't that smart.

Raj and Sheldon go out to a to test out the effects of the drug. Raj approaches a girl and stares at her silently for a moment.

The final scene shows Leonard, Sheldon, and Howard playing a confusing game of three-person chess, and Raj, who is completely naked, still under the effects of the drug.

Critics

 * The TV Critic: "I liked the simple way that situation unfolded. Penny suggested the lie in a simple flick of resentment but the less savvy Amy and Bernadette foolishly took her seriously. The transformation of Amy into a "typical" girl remains fun...The writers lost focus here and presented a fairly mediocre story. However the strong arc plot they have built up for the characters prevented this from feeling too irrelevant."
 * The A.V. Club gave this episode a B.
 * IMDb user reviews

Trivia

 * First episode to show Bernadette at Raj's apartment.
 * First appearance of Raj's bathroom.
 * When Sheldon is working on his three-person chess game, but is interrupted by a lonely Raj, he announces that he has company and later speaks to an empty chair for an aside. Apparently, he has created imaginary opponents to test his chess variant. In "The Porkchop Indeterminacy", Sheldon's twin sister Missy mentioned his imaginary colleagues during his childhood instead of imaginary friends.
 * Penny is the only one who does not share any scenes with the guys in this episode.
 * Before Raj leaves the apartment, he decides to wear his blue windbreaker which portrays his sadness. He then encounters Sheldon (wearing orange) at his apartment and theorizes that orange should resemble loneliness since it does not rhyme with any word.
 * A few episodes before "The Cohabitation Formulation", Priya states to Raj that if you eat beef, you will have to live with cows for three months and drink their urine but he disbelieves this portion of the Hindu code. In this episode, Raj tells Sheldon that he is taking medication that has a beta-blocker with an extract from cow's urine.
 * While Howard, Leonard, Priya, and Amy consider it implausible for Penny to date an astronaut causing Bernadette grief, Howard later becomes an actual astronaut in the next season.
 * First episode to show Bernadette's short temper and aggressive nature, a running gag in future episodes.
