Chris Cunningham's "Rubber Johnny"

This video is relatively old but still fascinating in some twisted way.

"Rubber Johnny documents a 16-year-old, inbred mutant's solitary existence, locked in a pitch-black basement by his ashamed parents. They all are TV-addict rednecks who occasionally feed Johnny and yell at him for making noise. Johnny's only company in the basement is his little horrified Chihuahua dog. His dog's I.Q. far outstrips Johnny's, who is a completely insane, bi-polar imbecile. Capable of morphing his body, he spends his life trying to amuse himself and his dog"
