William Shakespeare had a curse engraved on his tombstone to prevent anyone from moving his bones.
It's a pretty good practice to avoid incurring the wrath of the dead in general, but if there's a ghost you really don't want to upset, it's probably William Shakespeare's. Just think of the many inventive ways he killed people in his plays. That's why the curse on his grave at the Church of the Holy Trinity in Stratford-Upon-Avon should be taken seriously:
"Good friend for Jesus sake forbeare, To dig the dust enclosed here. Blessed be the man that spares these stones, And cursed be he that moves my bones."
It's thought that the warning was penned by Shakespeare himself. In his day, it was common for bodies to be exhumed for research purposes or even just to make room for more burials, and the Bard did not want that to happen to his remains. So far, his warning seems to have worked. Even when the grave received some repairs in 2008, workers said the stones would not actually be moved and the bones certainly would not be disturbed.
