Not sure if this makes me strange or not but I like to walk through old cemetaries. Especially ones in the 1800's.
Anyways, not sure if these are real sayings or just ones that are fun for ideas to use but here's a few for you to read:
"I told you it would end this way."
"Excuse my dust".
Not sleeping, just dead.
"If you want to dance on my grave, there's a cover charge and two-drink minimum."
"Hey! You! Stop stepping on my head!"
"I can't believe you wasted money on this! I said I wanted to be cremated!"
"Got in the last word."
