Storyline

Raj's sister, Priya, a corporate lawyer, has a 24 hour layover in Los Angeles on her way to Toronto on a work trip. When the guys met her the first and only time five years ago when she last was in Los Angeles, Howard and Leonard made a "pinky swear" pact not to hit on her, much to Raj's pleasure as he wanted and still wants to protect his little, innocent sister. Priya ends up not being so innocent as she wants to have a casual fling with Leonard on this trip, he who complies and would actually want it to be more than just casual. When Sheldon catches Priya in their apartment when she shouldn't be there, Sheldon devises an elaborate but totally implausible alibi for Leonard in the probability - at least in Sheldon's mind - that Raj and or Howard will ask. This incident brings up the issue of betrayal amongst the four friends. Written by Huggo

Quotes

Leonard Hofstadter: I admit it, I... I may have crossed a line here, but come on, Raj, your sister is a grown woman. And to her, I'm a forbidden piece of white chocolate.
Raj Koothrappali: [standing up to leave] I don't believe it. This is a terrible betrayal of my trust.
Leonard Hofstadter: No, no, no. Would it... would it help if I told you that I offered her my heart and she kind of stomped on it?
Raj Koothrappali: How hard did she stomp?
Leonard Hofstadter: Very hard.
Raj Koothrappali: [sitting down] Okay, I'm good.

Crazy Credits

CHUCK LORRE PRODUCTIONS, #306 Zen and the Art of Sitcom I have been writing sitcoms for twenty-five years. During this time, I have learned a few things. Practical things. Do's and don't's if you will. For instance, do hire actors based on talent not looks. Somewhere between take eight and take fifteen, you will be hating both yourself and the gorgeous, but clueless ingenue who got the job because she looks exactly like what you imagined the character looks like... or worse, like the kind of woman you could live happily ever after with. Don't waste time with a marginal joke that forces the actor to twist him or herself into a pretzel in order to make funny. It's much better to work a little harder and write a great joke that the actor can do in their sleep. This also allows the actor to be well-rested when it comes time to renegotiate his or her contract. Do try to be kind to the power players. The movers and shakers. The people who tell you how to do your job. After they fail in network TV, they will remember you fondly while they're busy tanking fledgling internet companies. But perhaps more important than do's and don't's is learning to trust in the mysterious power of intuition. The soft inner voice that guides you to a better outcome than experience and logic could ever provide. This is what I call the Zen of Sitcom. The willingness to allow transcendence to play a part in the making of a TV show. Try it sometime in your own job. It can be the source of great inspiration. A word of warning though: it's not foolproof. If your business collapses or you wind up getting fired, you're probably hearing the same voice I listened to when I created Grace Under Fire, Cybill and four or five TV pilots that now function as landfill. If it's possible, try not to listen to that one. As inner voices go, it's kind of a douche. See more »

Leonard wants Sheldon to keep a secret in "The Irish Pub Formulation" ep of "The Big Bang Theory"
2 October 2011 | by (Baton Rouge, La.) – See all my reviews

In this last season ep of "The Big Bang Theory": Raj's sis Priya (Aarti Mann) has come for a short visit with Raj warning Howard and Leonard to not hit on her. Howard reminds Raj about Bernadette but Leonard says nothing. That's because Priya has already hit on him and he reciprocates! They manage to spend the night in Leonard's apartment without Sheldon-who's busy with a video game-knowing but it's different when Priya has to leave the next morning. So in order to honor Leonard's request to not tell the others, Sheldon makes up a story about a red-headed Irish waitress at a bar who had designs on Leonard. Leonard simply wants his roommate to zip his lip but that's not so easy...Another very funny episode of "TBBT" especially when the confessions come fast and furious near the end. So on that note, "The Irish Pub Formulation" is highly recommend. BTW, if you're wondering why Kaley Cuoco is not in this one, she had broken a leg horse riding before the filming and was in the process of healing it.
