According to the
Bible, the
dowry that
David gave to
Saul for his
bride,
Michal.
1 Samuel 18:25-27:
When David wanted to marry the king Saul's daughter, he asked David to bring to him a hundred foreskins of the Philistines, that he may be avenged of the king's enemies.
David arose and went, along with his men, and killed two hundred of the Philistines; and David brought their foreskins which were given in full number to the king that he might become the king's son-in-law.
Moral: If you have a rough relationship with your father-in-law, follow the Biblical example: go out and kill 200 guys he doesn't like, then surprise him with a gift of 200 foreskins.
