What is the worst joke?

A woman works the night shift and a man follows her. This woman is scared. She passed by the cemetery and had a brainwave. She 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. At this moment, a grave robber emerged from the grave and said, Shit, I delayed my work and scared you to death! As soon as the voice of grave robbery fell, I found an old man carving a tombstone with a chisel. I was curious, so I asked him. The old man said angrily: NND, they carved my name wrong ... The great fear of robbing the tomb screamed and ran away. The old man sneered, "Shit, you dare to steal my business, and it's still tender ..." 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. Old man, stop fooling me and get down the hill! Then a scavenger climbed out of the grass. " Damn, it takes such a great god to make a piece of iron. "
