'Bill gets really excited when he comes home and finds one of his 7th Heaven episodes or sees that he's caught House IV on Cinemax,' friend Ray Morris said. 'Maybe he does it so he knows to watch for a residual check.' Morris said Katt also frequently scans his listing on the Internet Movie Database for errors.
