We can't get too graphic here, but word is that the action includes some bodily functions and an act known as a "Dirty Sanchez."
The sex vid's working title is "Saved by the Smell." Ewwwww.
I really don't care about this, mostly because I haven't seen that show (except a few episodes from the two weeks it was on Adult Swim for some reason). But words cannot explain how amusing I find this (especially the two quotes above).
