Don't go to jail joke

Two young guys were picked up by the cops for smoking dope and appeared in court on Friday before the judge. The judge said, "You seem like nice young men, and I'd like to give you a second chance rather than jail time. I want you to go out his 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 Honour, I persuaded 17 people to give up drugs forever." "17 people? That's wonderful. What did you tell them?" "I used a diagram, Your Honour. I drew two circles like this.....o O ... and told them this (the big circle) is your brain before drugs and this (small circle) is your brain after drugs." "That's admirable," said the judge. " And you , how did you do ? " the judge asked the second guy." Well, Your Honour, I persuaded 156 people to give up drugs forever." "156 people! That's amazing! How did you manage to do that?" asked the judge." " Well, I used a similar approach (he draws two circles).... o O I said (pointing to the small circle) "this is your asshole before prison......(pointing to the big circle) "this is your asshole in prison!"
