A scientist pulls a lever. The lever opens a hole in the floor and a dwarf falls into it.
The dwarf doesn't scream, but he does look pretty panicked. The dwarf reaches the bottom of the hole, but he doesn't die or break any bones.
After a couple of moments, he starts walking again. he keeps walking and walking until the hole gets so far away that he can't see it anymore.
When the dwarf reaches the other side of the planet, he encounters a bald, chubby guy eating a hot dog. The dwarf stops walking and the chubby guy finishes eating the hot dog.
After a while, the dwarf and the chubby guy start walking again. Soon enough, the hole in the floor opens up again, and the dwarf falls down into the hole. This time, the dwarf gets stuck in the bottom, and dies.
The scientist looks at his partner and smiles.
"It all works perfectly!" says the scientist. "Just as I calculated."
