Cupcakes role reversal

Michael invites Murderer to bake cupcakes however Michael bonks Murderer on the head with a hammer and Murderer wakes up in a chamber with lots of weapons. He then sees Michael cut off his arms and then chainsaws his belly and then cuts off his penis and then he screams and then the bed lays down and Michael gives a creepy look and murders Murderer to death and eats the cupcakes.
