Penny, Leonard and others in “The Cooper-Nowitzki Theorem”

I know this is none of my business, but I just... I have to ask -- what's Sheldon's deal?

What do you mean, "deal"?

You know, like, what's his deal? Is it girls…? Guys…? Sock puppets…?

Honestly, we've been operating under the assumption that he has no deal.

Come on, everybody has a deal.

Not Sheldon. Over the years we've formulated a number of theories about how he might reproduce. I'm an advocate of mitosis.

I'm sorry?

I believe one day Sheldon will eat an enormous amount of Thai food and split into two Sheldons.

On the other hand, I think Sheldon might be the larval form of his species and someday he'll spin a cocoon and emerge two months later with moth wings and an exoskeleton.

Okay, well, thanks for the nightmares.
