Two police officers who

conduct anti-drug programs at local high schools are comparing notes one day. The first notices that statistically

the second officer is far more successful at convincing the kids to stay drug-free and inquires about his

technique:

"How come I'm not getting the kind of results you are Jack? I use the technique they showed us

in the training program.... I draw two circles on the board, one large and one small. Then I tell them 'the big

circle represents your brain before drugs and the little circle is your brain after drugs'. How do you do

it"

"Well, I use the same drawing, but I tell them that the small circle is their butt hole before prison"
