This just in from Mark! He has uncovered the mystery of the Ancients!
“I actually know the punch line of that joke...my uncle is greek and that ditty has been passed down lovingly from generation to generation...usually at holiday time. "Seeing a eunuch, an Abderite asked him how many children he had. The eunuch replied that he had none, since he lacked the means of reproduction. Retorted the Abderite …you can have as many as you like…you just have to give them candy first" in the original version the word "pasteli" was used instead of candy but it has been updated over the years.”
