Tata: Hey! When I got here this morning, there was a ball of yarn on my desk.

My cellmate: I found it when I was cleaning out my guest room. It’s even got one of those hook things. You want it?

Tata: Sure. It’s not your yarn, is it?

My cellmate: No, I don’t knit or whatever.

Tata: And you don’t know where it came from or why?

My cellmate: No idea.

Tata: This confirms my theory, you know.

My cellmate: You have a theory?

Tata: There’s a ball of yarn in every house. No one knows why.

My cellmate: Interesting. I expected more cheese.
