Quotes (43)

Raj: Ooh, Leonard is going all alpha nerd on Sheldon's ass.

Sheldon: I'm not saying that all senior citizens that can't master technology should be publicly flogged. But, if we made an example of one or two it might give the others incentive to try harder.

Raj: Last night I had a dream we got so rich from the app, you and I bought matching side by side mansions, but there was a secret tunnel connecting your front yard to my back yard. What do you think that means?

Leonard: I had a great idea. Do you know how we're always having to stop and solve differential equations, like when you're doing Fourier equations or using the Schroedinger equation?
Sheldon: Howard doesn't, he's only an engineer.

Sheldon: Hear me out. The atomic bomb was the Manhattan project, Windows 95 was Project Chicago, for our app I humbly suggest Project Nodlehs.

Look forward to this show weekly even the re-runs. Then talk about it at work the next morning. I look forward to Thursday night just to watch this show...

Sent an email to C4 about the announcement that this was the last episode, and they responded that this was an error by the announcer. However we will have to await the complete rerun of the series before they air the last two - all to do with timing and the dates of airing in the US

Why have channel 4 in the uk said this is the last episode in this season. Why it's clearly not. Why ! will I have to illegally down load from some site? Great show might have to buy me some bus pants.

Hmmm this was aired last night and it was announced that next week would be the last episode....is the channel fibbing?

But of course engineers use Fourier (and all transformations). I found Sheldon's comment really offensive. Oh well, physicists can't program!
