On Halloween night, two men were walking home after attending a masquerade ball. As they passed by a cemetery, they had a sudden urge to cut through it. However, when they were halfway through, they were startled by a rhythmic knocking sound - "knock, knock, knock." The sound echoed from a dim corner of the cemetery, sending shivers down their spines.
Confused and terrified, they looked toward the source of the sound and saw an elderly man holding a chisel, busily working on a tombstone. One of the men gathered the courage to speak, "Oh my goodness, sir, we thought you were a ghost! What are you doing here so late at night?"
The old man angrily replied, "XXX, they misspelled my name!"
