The Dark Backward (1991)

The Dark Backward is a twisted adventure from the demented mind of Adam Rifkin (Detroit Rock City) that tells the tale of a struggling comedian/garbageman (Judd Nelson) who grows a third arm out of his back and, with the encouragement of his pal Gus (played brilliantly by Bill Paxton), becomes an overnight sensation.

This film pretty much has it all: A ridiculous story, a crazy ensemble cast (including James Caan, Wayne Newton, and Rob Lowe), a kooky soundtrack, over-acting and quite a few gross-out scenes. It even has it's own product line called "Blumps".
