I Need My Sister Tamar to Come and Cook Me Food in Front of Me

Amnon tells David that he wants his sister Tamar to make him heart-shaped cakes. The advice is taken right out of the book of judges, but it doesn't go far enough for a real attempt at marriage. Amnon lays down and pretends to be ill in order to get some mosaic law help from King David. He's not even going to bring this up to David so there's no chance they would say yes.
