So two potheads have been charged with possession and both plead "no contest." The judge decides to be lenient on them and not give them any time if they spend the next 24 hours reforming evil drug users. (Must have been a first offense.)
They return to the courthouse the next day and the judge asks them how many people they've gotten off drugs. The first guy says, "Twenty-four!" "Amazing," says Hizzoner, since that's about 12,000 times better than the statistics. "How'd you do it?" "Simple," says the head. "I just show them: 'O' - This is your brain; 'o' - this is your brain on drugs."
"Impressive," says the judge. Turning to the second head, he says, "And how did you fare?" "Yer honor, I saved 233 souls from the bonds of the evil weed." "And how did you manage that?" "Kinda the same as the other guy, 'cept I told people: 'o' - this is your ass hole; 'O' - THIS is your ass hole in prison."
