There is one urban legend in particular that creeps out a lot of people.
The story goes that sometime in 1989, Russian scientists in Siberia had drilled a borehole some 14.5 kilometers deep into the Earth's crust.
The drill broke through into a cavity, and the scientists lowered some equipment to see what was down there.
The temperature was about 1,100°C (about 2,000°F), but the real shocker was the sound that was recorded.
They only got about 17 seconds of audio before the microphone melted, but it was 17 horrifying seconds of the screams of the damned.
