The Euclid Alternative

Gives a rare camera view of Leonard and Sheldon's apartment, from the vantage of the hallway that's normally seen to the back right, going to the bedrooms, allowing us to see the "4th wall" in the front of the apartment the camera normally sees through.

As initially noted in this episode, and continually referenced throughout the series, Penny's car is displaying a check engine light. The car is seen to be a Mk1 (first generation) Volkswagen Rabbit Cabriolet, sold in the US in the early 1980's. This vehicle does not have an on-board diagnostic system, thus is not equipped with a check engine light.

CHUCK LORRE PRODUCTIONS, #220 Friday morning, October 10, 2008 Watching the market fall as precipitously as the hopes and dreams of NBC and ABC executives, I can't help but think that there are two bets I can make right now. One is on the simple inertia of a world economy created by hundreds of millions of people creating and servicing stuff that other people need and want. The other bet is on canned goods and guns. Since I've never actually fired a weapon and I'm not sure where my can opener is, I've decided to go with bet number one. If I'm wrong and the market continues to descend like a drug-addled hooker with vertigo, it's reasonable to assume that any new world order created by the complete collapse of the free market system will have little use for a comedy writer. For that reason I think it only prudent to hedge my bet. This weekend I plan on learning a few new survival skills, beginning with foraging for berries and hiding from people whose skill set includes shooting wildlife from helicopters.
