Provide a joke about grave robbers.

A woman works the night shift and a man follows her. The woman was afraid and passed by the cemetery. She had a brainwave and said to the grave, Dad, I'm back. Open the door. The man was frightened and ran away screaming. The woman was relieved and was about to leave when suddenly a gloomy voice came from the grave: Daughter, you forgot your key again. The woman was frightened and ran away screaming. At this time, a grave robber emerged from the grave and said, I'm afraid of delaying my work and scaring you to death! As soon as the voice of grave robbery fell, I found an old man carving a tombstone with a chisel. Out of curiosity, the old man said angrily, they carved my name wrong. The taboo of grave robbery ran away screaming. The old man sneered, "How dare you rob me of business …" Just then, the chisel accidentally fell to the ground and the old man was about to pick it up. When he bent down, he found a chisel in his hand in the grass. The old man was shocked, and suddenly a voice came: "You want to die! Change my house number! " . The old man was scared out of his wits and rolled down the hill! At this time, a scavenger climbed out of the grass: "Hey, it's so hard to get a scrap iron these days."
