Haapajärveläinen hautuumaa

One dark night two men were walking home in Haapajärvi 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!"
