Two young guys were picked up by the cops for smoking dope. On Friday, they appeared in court before the judge.

The judge said, "You seem like nice young men, and I'd like to give you a second chance instead of jail time. I want you to go out this weekend and try to show others the evils of drug use and get them to give up drugs forever. I'll see you back in court Monday."

Monday, the two guys were in court, and the judge said to the first one,

"How did you do over the weekend?"

"Well, your honor, I persuaded 17 people to give up drugs forever."

"Seventeen people? That's wonderful. What did you tell them?"

"I used a diagram, your honor. I drew two circles, one bigger than the other...

...and told them that this [pointing to the big circle] is your brain before drugs, and that this [pointing to the small circle] your brain after drugs."

"That's admirable," said the judge. Then he turns to the second boy. "And you, how did you do?"

"Well, your honor I persuaded 156 people to give up drugs forever."

"Wow!" said the judge, "156 people! That's amazing! How did you manage to do that!?!"

"Well, I used a similar approach," the boy said.

"I just pointed to the small circle and said, 'This is your asshole before prison'...."
