copied from Carolyn Harper Johnson of Michigan:
Two men were walking home after a party and decided to take a shortcut
through the cemetery just for laughs. 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 found 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
scared us half to death -- we thought you were a ghost! What are you
doing working here so late at night?"
"Those fools!" the old man grumbled. "They MISSPELLED MY NAME!"
