In Sheldon's view, the tenants in the apartment directly above his and Leonard's are perfect neighbors since they never make any noise and he doesn't even know them. So he is horrified when he learns they are moving. Sheldon's fears are laid to rest when he questions the new tenant, Alicia, who is an aspiring actress like Penny and who answers all his questions on her living habits correctly to his specifications. Leonard, Howard and Raj, on the other hand, are more than happy as Alicia is a beautiful young woman. As Leonard, Howard and Raj fawn over Alicia, Penny becomes jealous. Penny does whatever she can to compete with Alicia and regain what she believes is the loss of her queen bee status within the group. But equally as important, Penny wants to expose Alicia's motives for her friendship with the guys.
Did You Know?
When Alicia holds the clipboard over the milk crate, her left hand is on the top. It then cuts to a closer shot and her hand is on the side. Then in the next shot, she's suddenly writing on it. See more
[Sheldon shakes one of the boxes of the new tenant
What are you doing?
I'm checking for musical instruments.
[Shakes the box again
Does that sound like castanets to you?
The box says "kitchen".
So? Do cocaine smugglers write "cocaine" on the box?
CHUCK LORRE PRODUCTIONS, #247 The quantum physics joke Penny tells the guys in tonight's episode was told to us by Nobel award-winning physicist, Dr. George Smoot. Penny tells it in about twenty seconds. Dr. Smoot's version probably took about three minutes, although it felt a lot longer. No one had the heart to tell him to get to the punch line, proving my hypothesis that in addition to time slowing down as you accelerate, it also grinds to a halt when you're being courteous to a genius. Thanks for the joke, Doc! See more
