Two men were walking home after a Halloween party and decided to take a shortcut through the cemetery just for fun.  Right in the middle of the cemetery, they were startled by a tap-tap-tapping noise coming from the misty shadows.

Trembling with fear, they finally saw an old man with a hammer and chisel, chipping away at one of the headstones.

"Holy cow, mister!" one of them said after catching his breath.  "You nearly scared us to death - we thought you were a ghost!  What are you doing working here so late at night?"

"Those fool!" the old man grumbled exasperatedly.  "They misspelled my name!"
