Don't forget the blood and guts in Nip/Tuck. Great show, but it's the first one I thought of when they mention "worst shows for family viewing." Let's not forget the little affair between the tutor and the kid either.
Or even more salacious, the tutor's kid with the other kid. I sometimes think that there is no script and the director just releases everyone on set and says rub up against anyone within an arms length.
