Basically a one minute episode. A large ghoul dressed in black frock coat and a top hat on his skeletal head is standing in an elevator. A normal looking man enters the elevator unphased by the ghouls presence.
When the elevator doors open a young woman enters, also unpeturbed by the sight of the ghoul. The normal guy takes his hat off in the ladies presence. The ghoul notices this and moves to take his top hat off as well. Instead he removes his entire head with the hat still on it.
An amusing take on the old phrase "chivalry is not dead."
