Come, let us make our father drink wine, and we will lie with him, that we may preserve seed of our father. And they made their father drink wine that night: and the firstborn went in, and lay with her father; and he perceived not when she lay down, nor when she arose. Behold, I lay yesternight with my father: let us make him drink wine this night also; and go thou in, and lie with him, that we may preserve seed of our father. And they made their father drink wine that night also: and the younger arose, and lay with him; and he perceived not when she lay down, nor when she arose. Thus were both the daughters of Lot with child by their father.
(Genesis 19:32-36)

Heh!

It just means, If there are no acceptable men to be found in the area, a woman shall ply her father with wine and have sex with him in order to produce progeny to carry on the family name.

HEH! Sorry, I just find that funny.
In a sick, funny way.
Bleargh.
Heh.
