I didn't watch Kaysar in his seasons, however I did see this video of Big Brother House Calls, where he does an interview talking about the Big Brother game. I'm not sure how many people might have seen this video, but at one point the host reads out some letters, including one in which a woman talks about having a foot fetish and wanting to see Kaysar's feet. He actually goes along with it and takes off his shoes and socks and puts his bare feet up on the table
I found the video here:

But you may have to search google to find it uploaded elsewhere if you're living outside of the U.S. Google search "Big Brother house calls 04.15.08". I'll get screen caps as soon as my internet cooperates.
I believe it starts after the 21 min. mark.
