Storyline

Bernadette and Howard discuss where their relationship is heading when Howard once again can't stay the night since he has to look after his mother. When Bernadette broaches the topic of them moving in together, Bernadette ultimately gives Howard an ultimatum: her or his mother. When she asked him this question, she didn't anticipate what Howard wants in a house-mate, sexual partner or not. Meanwhile, Raj's sister Priya is back in town on business. Knowing that Leonard and Priya had casual sex last time she was in town with Leonard wanting their relationship to progress further, Raj refuses to let Leonard see or speak to Priya. But Priya and Leonard do speak, and much to Raj's anger, they decide to start seeing each other. But one other person may be affected by Leonard and Priya dating: Penny. Although Penny outwardly says she is happy for Leonard, Amy, as her new BFF, wants to provide some comfort to Penny, all the while gathering some scientific data. Written by Huggo

Quotes

Priya Koothrappali: So, Penny, Leonard tells me you're an actress. That must be pretty exciting.
Penny: Oh, yeah, yes, real great. Today I drove to Van Nuys for an audition I thought was going to be for a cat-food commercial. It turned out to be porn.
Sheldon Cooper: Did you get the part?
Penny: I didn't do the audition!
Sheldon Cooper: Given the state of your career, can you really afford to be picky?

Random Things I've Learned in TV

Never ask a question when you know the answer is going to be a lie.

Silence is always bad news.

Strong Nielson ratings guarantee employment, not self-esteem.

Actors can smoke cigarettes because they're immune to carcinogens.

It's safe to talk openly and honestly with people because they're not really listening.

The two major groups in TV show biz are, naturally enough, show people and biz people. Telling them apart is simple. No matter how old they are, 'show' people (usually creative types like writers, actors, directors and musicians) dress like teenagers. Again, regardless of age, 'biz' people (agents, managers, lawyers, company executives) dress like adults. When 'biz' people start dressing like 'show' people it means they've made too much money off the backs of the aforementioned 'show' people. When 'show' people (usually directors) start dressing like 'biz' people, it means they're insecure about their creative involvement and need a hug. See more »
