Very Bad Things was the first one that came to mind for me. Good movie. The ending makes it worthwile even if oyu dont enjoy the rest of the movie.

Fargo would be my next choice.

Little Murders
Happiness

Black comedy? Well I love Chris Rock's work, and Eddie Murphy made some very funny movies in his career. If you can get old tapes of The Cosby Show, that's a classic too.

Seriously, though...

Pulp Fiction.
