Pilot

Leonard (Johnny Galecki) states that the combined IQ of Sheldon (Jim Parsons) and himself is 360. In a later episode of season 1 Sheldon states his IQ as 187 meaning that Leonard's IQ is 173.

The experiment discussed by Sheldon (Jim Parsons) at the very beginning of the episode is a quantum version of the well-known "experiment," but incompatible with the work presented on the whiteboard. His dialogue was meant to accompany the whiteboard seen in the unaired episode Unaired Pilot (2006).

CHUCK LORRE PRODUCTIONS, #182 Back when I was writing and producing Dharma and Greg, the only way to read my cards was to record each episode on a VCR and hit the "pause" button. This was not an easy task. The image wobbled like crazy making the tiny words of my weekly tomes very hard to see. Then it hit me. What about building a device that records video images digitally? Wouldn't this allow for a much more precise "pause" function? I took my little notion to an impoverished computer whiz by the name of Schlomo Tivowitz. At the time of our meeting Schlomo was feverishly trying to invent an improved version of the George Foreman Grill. Schlomo's grill would contain a hard drive that remembered all the details of your last barbecue, as well as an address book. I didn't really see the point of it, but, not being a tech guy, I held my tongue and presented him with my idea. I will never forget his reaction. With hamburger-flecked spittle flying from his blubbery lips, he laughed, called me some very unkind names and demanded that I leave his mother's basement immediately. My hopes dashed, I went back to work on Dharma and forgot about my silly idea. Well, I'm sure you can figure out what happened next. The fact that you're reading this card right now should tell you. Thankfully, it's not in my nature to be bitter. But there are times when I feel a little used -- usually when I've forgotten how to effectively grill a fatty piece of chicken.

The syndicated version of the episode cuts out the entire sperm bank storyline at Chuck Lorre's insistence because it does not fit later established facts about the character of Sheldon Cooper.
