Episode Quotes

Rajesh: Missy. Do you enjoy pajamas?
Missy: I guess.
Rajesh: Yes, well, we Indians invented them. You're welcome.
Howard: Yeah, well my people invented circumcision. You're welcome.

Howard: Well, she's free to examine my briefs.
Leonard: Howard!
Howard: I know! I'm disgusting. I should be punished. By her. Oh, look I did it again.

Sheldon: Eat this slice of cheese without farting and you can sleep with my sister.

Wolowitz: Is it 'cause I'm Jewish, 'cause I’d kill my Rabbi with a porkchop to be with your sister.

Sheldon: You're out, too, by the way.
Leonard: Say what?
Sheldon: It's nothing personal, I'd just prefer if my future niece or nephew didn't become flatulent every time they eat an Eskimo pie.


When Sheldon's sister comes to town, Sheldon reluctantly lets her stay at his apartment instead of the hotel she had booked. Leonard, Howard and Raj are all smitten by Sheldon's twin, Missy, and compete with each other to win her fancy. When Raj's selective mutism prevents him from talking to Missy, he signs himself up for an experimental drug.

After being creeped out by the guys' advances, Missy goes out with Penny to get their nails done. In a sneaky effort to try win over his sister, Leonard tells Sheldon he should be taking an interest in who Missy is with in order to protect her genetic lineage, which could one day produce another remarkable intellect like Sheldon's. Sheldon accepts Leonard's argument but instantly dismisses all three of the guys as unsuitable for his sister.

When Missy witnesses Sheldon telling the guys they're not good enough for her, she demands to see Sheldon in his room where she explains he does not have a say in who she dates. Sheldon informs the guys he no longer has any say in the matter, and they decide to vie for Missy's affection in a more restrained manner.

Leonard, Howard and Raj each visit Missy, who is now staying in Penny's apartment, to try win her over. Only Raj seems to have made a positive impression on her, though his efforts are for nought when his medication wares off and he can no longer speak to her. Missy returns to Texas with none of the guys having successfully courted her.
