A young preacher was contacted by the local funeral director to hold
a grave-side committal service at a small local cemetery for someone
with no family or friends. The preacher started early but quickly got
himself lost, making several wrong turns.

He arrived a half-hour late, the hearse was nowhere in sight, and the
workmen were eating lunch.

The pastor went to the open grave and found the vault lid already in
place.  Taking out his book, he read the service.

As he was returning to his car, he overheard one of the workmen say:
"Think we should tell him it's a septic tank?"
