‘Killer Mannequin’ is a three part horror-comedy sketch which aired on “Madtv” during the 5.16 (Feb 2000), 6.6 (Nov 2000), and 6.28 (June 2001) episodes.
In the sketch, a serial killer poses as a mannequin in a department store to avoid detection as he murders his victims. Not even the cops can stop him from killing…mostly because they think he’s just a mannequin.
This one is pretty bad, but a golden oldie.
