What to do about my father-in-law?

Set the dogs on the ungrateful cretin, throw the bugger out of his estate and send him to the local Salvation Army Citadel, that is where I sent my mother when she got to old to work in Smythe Hall kitchens as a scullery maid. To much emphasis is placed on helping dreadful sponging relatives these days, get rid of him quick before he becomes a major problem.
