Everyone knows that Pennsylvania Zombies are particularly attracted to towns and cities which end in “burgh” with an “H.” This is why all the other places in PA that end in “burg” dropped the “H.” Pittsburgh was warned when they decided to keep that letter that it would attract the undead. They only have themselves to blame.
And, yes, it’s true. Pittsburgh is the only place in the state that spells burgh with an “h.” Fat lot of good that letter will do them when zombies are eating their faces off.
