The female lead is said to have been a stripper; the cameraman zooms in on her cleavage and backside once or twice.
Two of the main guys are seen shirtless a few times; in one scene, one is shown rubbing oil on himself.
About a second of a sex tape is spliced into the main footage (the gag is that the movie was taped over a home video);
a woman is shown talking dirty, no nudity.
In a scene parodying "Paranormal Activity", the male lead shares a bed with the couple whose home he's investigating; both the man and the woman touch his leg and/or buttocks, and at one point he leaves the room and re-enters wearing a cocktail dress.
Another woman's cleavage gets some screen time.
The main guy and girl engage in detailed, euphemism-laden phone sex.
While lost in the woods, a guy calms himself down by imagining a vacation at a nude beach.
