Two young guys were picked up by the cops for smoking dope and appeared in court last Friday before the judge.

Monday, the two guys were back in court. The judge asked the first guy, "How did you do over the weekend?" "Well, your honor, I persuaded 17 people to give up drugs forever." The judge was quite impressed and said, "Seventeen people? That's wonderful. What did you tell them?"

The first guy said, "I used a diagram, your honor. I drew two circles like this:

"And told them this (the big circle) is your brain before drugs and this (small circle) is your brain after drugs." "That's admirable," replied the judge.

"And you, how did you do?" the judge asked the second guy.

"Well, your honor I persuaded 156 people to give up drugs forever." "156 people! That's amazing! How did you manage to do that!" The second guy answered, "I used a similar approach." (He draws two circles)

The second guy continued, "Well, I said, (pointing to the small circle) this is your ass BEFORE prison...................."
