Big circle little circle

Two drug dealers get brought before a judge. The judge says
that if they could get others to stop selling drugs over the
weekend that they would be found innocent.
That monday the judge said to the first one how many people
did you get to stop doing drugs? He replied 15. The judge said
very good how did you do it? The reply was I drew a small circle
and a big circle and said that the small circle was your brain
after doing drugs. The Judge said ok; how about you he said
while pointing to the second guy. The reply was I got 1500
people to stop. The Judge said How in God's name did you get so
many to stop. The guy said I also drew a big and little circle
and said that the little circle was your asshole before jail.
