 In the first half of the film, Angus (Jake Busey (qv)) makes  reference to a story where a wife kills her husband with a leg of  lamb. The story is "Lamb to the Slaughter" from Roald Dahl (qv)s  book "Tales of the Unexpected". Many will recognize this plot from a  classic 1958 episode of _"Alfred Hitchcock Presents" (1955)_ (qv).
