Are there any jokes about innovation

The woman works the night shift, the man follows her, and the woman is afraid. Passing by the grave, I 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. 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 next to him. The old man said angrily: NND, they carved my name wrong ... the taboo of grave robbery screamed and ran away. The old man sneered, "Shit, you dare to steal my business, 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, it takes such a great god to get a piece of iron."
