I would just adopt him as a grandparent and take care of him
From what I have seen of him on tv, he seems like good company if nothing else. They both know why they are doing it, business arrangement I guess.
I Don't think it's a matter of s*x. I would say its more for image,and a young pretty girl helps him to feel younger. She'll have a lot of fun in that house and i'm sure she will be well taken care of. He has got a great sense of humor.
then you have never seen his Flesh hoagie
