Quotes (34)

*Sheldon is using a map of the U.S. to find out where he can move*
Sheldon: Penny, you're from Nebraska, right?
Penny: Born and raised.
*Sheldon crosses out Nebraska*

Sheldon: I do not have to urinate. I am the master of my own bladder. Drat.

Sheldon: My new computer came with Windows 7. Windows 7 is much more user-friendly than Windows Vista. I don't like that.

Sheldon: It's all right, they didn't take my comic books.

Sheldon: I'm fine. Although I'm no longer master of my own bladder.


The guys are eating out at the Chinese restaurant, although Sheldon is disturbed to find they've revamped the menu. Sheldon is perplexed to find a new item on the menu, "Shrimp in Mobster Sauce". The guys decide to go to Corleone's and have pizza instead. On their way home, Sheldon is still thinking about the Mobster Sauce. When Leonard and Sheldon arrive back at the apartment, Leonard notices the is broken open. They discover their TV and laptops are gone, so Leonard grabs the phone to call the police, while Sheldon goes to check on his comic books. 

The police have arrived and Sheldon is detailing the video games and consoles that were stolen. After the police leave, Leonard and Sheldon sit on the couch. Sheldon decides to watch TV on his iPhone until the criminals "return to bludgeon them to death" in their sleep. When Sheldon finally goes to bed, he barricades the door, only to need the bathroom a few minutes later. Sheldon gets up and goes over to Penny's apartment to get her and Leonard, as it's too scary for him to be in the apartment on his own.

Later that night, Sheldon and Penny are playing pictionary. When Leonard and Penny go to bed, Sheldon watches TV on his cell phone. After watching a murder scene, Sheldon runs to Leonard's bedroom. The next day, Howard and Raj have installed a state-of-the-art security system. When Penny walks into the apartment, she sets it off and gets caught in a net. That night, Sheldon hears a sound. Instead of opening his door to investigate, he crawls across the outdoor ledge of his window to Leonard's room. Leonard and Penny explain that they knocked over a lamp. Sheldon, with his mind at rest, goes to get some warm milk and check the perimeter. On his way, he accidentally sets off the security system and gets caught by the electrified net.

Having been robbed and later attacked by his own security system, Sheldon looks for somewhere safer to live. Sheldon eventually settles on Bozeman, Montana. Howard and Penny try convince Sheldon to stay, but he refuses. He says good-bye in a prepared video and leaves the apartment. When he arrives in Bozeman, his luggage is stolen by a young man who offered to help. Sheldon immediately buys a bus ticket back to Pasadena.

I remember the review of The Big Bang Theory's first season. It did not rate high and they said it would not last. Who is laughing now. I do not miss an episode and I even watch the reruns on TBS. Great show!!!!

Thrice damn! Typo- both proton and neutron.

An otherwise fine episode ruined by a grevious lack of attention to detail. I take great issue with Sheldon indicating in Pictionary a drawing of a Bohr Model of an atom and naming it a hydrogen atom. It is clearly a deuterium atom as it has both a proton and an electron. Although deuterium is an isotope of hydrogen and therefore hydrogen is technically correct, deuterium is more exact and it stretches the bounds of believability that Sheldon would be less than fully exact. This dreadfully imprecise writing jarred my suspension of disbelief into the next dimension and ruined the episode for all scientifically literate viewers.
