Real Murder Mystery Party

A casually dressed visitor arrives with a bottle of soda just as an eccentric group begins a blackmail-fueled evening. When the lights go out and bodies start falling, he tries to call the police and stop the guests from wandering off. The others prefer dramatic accusations, concealed weapons and increasingly lethal deductions, leaving him to impose some practical rules on the mystery.

The official video description also calls this sketch “Clue Dun It.”
