The context of the following conversation is To get lee to sleep that night, Jesse started telling lee a story.:
Jesse says Lee didn't want to sleep last night, so I told him a story..
The friend responds Let me guess, it was the one about the counting sheep!.
Jesse responds How'd you figure that one out? Yeah, it is an oldie but a goodie. Puts them right to sleep..
The friend responds Any story about numbered sheep jumping over a fence would put an insomniac into slumber, Jesse..
Jesse responds Yeah, that's true. I would do it in my own head to put me to sleep..
The friend responds I've done it before, too. I usually get around to the 10th sheep and then I'm out..
