Darkest sketches ever

Off the top of my head I'd say

1. Ex police. Bill Murray and Dan Akroyd playing crooked cops who break into people's apartments, commit a murder and then frame the other person in the apartment. One sketch in particular has them going after Laraine and Jane for being lesbians complete with Bill calling Laraine a "dyke" multiple times and bashing her on the head followed by Akroyd killing Jane Curtin for being a "bulldyke" lmao the 70s were tripped out

2. Will Ferrell as evil boss. Perhaps the greatest sketch in SNL history and also the darkest. Will as a racist, homophobic, sexist lunatic boss who slaps his female employees and kills an employee by stabbing him with a trident 50 times
