Who: Narrator, a Grim Reaper
Narrator hates Hell and is bored, so decides to play a prank on a Grim Reaper by stealing his scythe.
The Grim Reaper realises it is missing, but being a Grim Reaper, he has a sixth sense or something of the sort and can tell where it is and who took it.
The Grim Reaper confronts the Narrator.
The ground gives way and the narrator falls deeper into the pits of Hell.
