The priest asks, "Rabbi, be honest, before you were a man of God, did you ever try ham?"
To which the Rabbi replies, "Yes, I used to like ham very much, but since it is against my faith, I no longer eat pig products." After a short pause the Rabbi turns to the Priest and asks, "Father, before you were a man of the church did you ever engage in sex with a woman?"
Blushing, the Priest responds, "Yes, to be honest, I did have sex before I entered the Priesthood, but as I must be celibate for Christ, I no longer partake in temptations of the flesh."
The Rabbi smiles and says, "A lot better than ham, isn't it?"
