There were three people. A chinese,an american, and a German stuck in a house with no doors, windows, and it had spikes on the walls.
The American said he would climb up the spikes to the top then throw down a rope, he did. That night they heard a scream, the next morning they found him on the ground holding his elbow. They asked him what happened and he said I fell down and broke my elbow.
So the German sais maybe he will have better luck so he climbs up. That night they hear another scream, the next morning they see him on the ground holding his knee. They ask him what happened and he said I fell doan and broke my knee.
So the Chinese said he always thought he was pretty lucky and that he would climb up this time. That night they a hear a blood-curdling scream. The next morning they see him on the ground holding his crouch, they ask him what happened and he sais: Ching Chan Chinese Balls Hanging from the Spiky Walls!
