Note: Per a gentlemen's agreement, I cannot reveal from whose blog this joke was stolen.
The President [Abraham Lincoln] told of a southern Illinois preacher who, in the course of his sermon, asserted that the Saviour [sic] was the only perfect man who had ever appeared in this world; also that there was no record, in the Bible or elsewhere, of any perfect woman having ever lived upon the earth.
Whereupon there rose in the rear of the church a persecuted-looking personage who, the parson having stopped speaking, said "I know a perfect woman, and I've heard of her every day for the last six years."
"Who was she?" asked the minister.
"My husband's first wife," replied the afflicted female.
