I generally dont do reality tv. I find COPS amusing sometimes, probably the original reality TV show. I've watched the Osbournes and American Chopper. That's about it.
Only 3 must see shows on TV for me, in order of preference are The Shield, Deadwood and Sopranos.
Beyond that, TV is usually on, but just for background, and it's very likely that it's on something like Discovery, History Channel, or a movie on HBO, StarZ or one of their brethren...
With all that said though, I have to admit "The Casino" has sparked my attention....
