The living have the opportunity to engrave in stone some thought appropriate to the character, or circumstances surrounding the death, of the deceased individual. Some epitaphs are unique and very revealing. It is difficult to find anything entertaining about a death, but on occasion, death can be humorous and bizarre. Sometimes, humor can be found where least likely. Cemeteries, for example, can be startlingly funny to the uninitiated.
Many epitaphs are unintentionally, and sometimes, intentionally, amusing.
Conceivably, the stonecutter or the family members did not realize how future generations would look upon their attempt to memorialize the deceased loved one. And on these lines do cast an eye. Prepare for death and follow me. Which is not funny at all. Which way you went.
