This graveyard joke is dead serious.

To fight the dumping of construction debris and other litter at Philadelphia's historic Mount Moriah Cemetery, volunteers who tend to the grounds have placed tongue-in-cheek signs around the graveyard that inform would-be litterbugs that they will be both "prosecuted" and "haunted by the interred."

Alas, the threat of being harassed by the ghosts of Revolutionary and Civil War soldiers — who are among the estimated 140,000 people buried at the cemetery — has done little to deter contractors from unloading their construction garbage on the hallowed grounds, said Ken Smith, a volunteer and board member with the Friends of Mount Moriah Cemetery. He described combating the constant dumping at Mount Moriah, which spans across sections of Southwest Philadelphia and Yeadon, Delaware County, as a longstanding battle.

"I think the signs are just kind of whimsical for the rest of us to drive by," he said. "It kind of makes the battle we're facing against the dumpers a little more tolerable."

The graveyard, which opened in 1855, is still owned by the original organization that founded it, the Mount Moriah Cemetery Association, even the association has no living members today. The Mount Moriah Cemetery Preservation Corporation, composed of officials and citizens from Philadelphia and Yeadon, became the court-appointed receiver of the property in 2014. Receivership allows the corporation to handle the cemetery's business affairs, even though it is not the owner of the property.

But since 2011, the boots-on-the-ground work of pruning, cleaning and overseeing the more than 200-acre graveyard has been done by volunteers with Friends of Mount Moriah Cemetery. When the group took on the task, the cemetery was already teeming with dumped construction debris.

"When we came in 2011, we were filling up 40-cubic-yard dumpsters and pulling out sofas," Smith said. "The first year we pulled well over 1,000 tires from the cemetery."

The small but dedicated group has watched brazen litterbugs come into the cemetery and dump piles of trash while they were working to clean the space.

"It's really a kick in the teeth whenever you see someone disrespecting the grounds and the people who are interred there," Smith said. "Unfortunately, it's just a battle we have to continue to fight."

The group was so fed up with the dumpers that one of the volunteers who owns a Havertown print shop made the signs and the group placed them around the cemetery several months ago, Smith said. A recent Instagram post of the sign sparked our interest, so we decided to find out the story behind it.

While the sign's joke may not knock 'em dead, there's always a chance the dead might come knocking if these trash litterbugs don't take heed.
