In a Thurmont, Maryland, cemetery:

Here lies an Atheist
All dressed up
And no place to go.

In a Georgia cemetery:

"I told you I was sick!"

Remember man, as you walk by,
As you are now, so once was I,
As I am now, so shall you be,
Remember this and follow me.

To which someone replied by writing on the tombstone:

To follow you I'll not consent,
Until I know which way you went.
