The Wal-Mart Prophet

There is a Wal-Mart somewhere in Indiana, with a concealed trapdoor in the frozen food section.

If you tap on the door three times with your left foot, a voice will ask you for a toll.

Open the trap door, put three lemons inside, and close the door.

After ten seconds, you will hear a knock on the trapdoor and find a red piece of paper that tells you two of the following three things: the exact location of your death, the manner of your death, or the exact date and time of your death.
