The Rocky Horror Picture Show The Criminologist, An Expert (Charles Gray)

CSI: Denton

Because Rocky Horror was based on a musical play, it has a narrator. The narrator takes the form of a criminologist, telling us the weird story of "the Denton affair." He's normally very serious, but even he loosens up and does "The Time Warp" in his office all by himself.

When he's not doing the pelvic thrust (that really drives him ins-a-a-ane), his narration gives the movie the feeling of a cautionary tale. It parodies fear of sexual awakening by cautioning viewers not to get involved with weird, sexy aliens…lest the same fate befall you.
