K...I hate that you are having this problem. We have 12 cats and we still have this exact same problem. Luckily we live in the country and I can put the wild one outside for awhile when she gets tooo crazy. Of course, that does calm her down.
I think cats gravitate to animals/people that don't want to be bothered with them. My Dad hates cats...when he comes over..yup...he ends up with 2 or 3 on his lap...while he is grimacing.
I hope you can find something that the cat likes to play with more than the old man...I feel sorry for the old guy.
