The disease responsible for any
man needing to become circumcised in adulthood instead of as a

First guy: I was circumcised at 22 because my
foreskin wouldn't retract properly.
Second guy: A likely story. Admit it - you had knob rot!
Third guy: Three words,
dude - soap. And. Water. Keep it clean next
time!
