8. Gravedigger Billy
Gravedigger Billy appeared in the 2005 episode "The Girl Who Slept Too Little" as groundskeeper Willie's deranged, grave-digging cousin. Billy works at the cemetery next to the Simpson home at 742 Evergreen Terrace, and freaks out Lisa one evening when she sees a hand burst out of a freshly-dug grave. Billy had buried a man alive and stole his watch, and when he sees the hand, whacks it with his shovel. Billy has a fractured relationship with Willie, who he looks identical too, and even tricked his cousin to walk into the cemetery luring him with a pot of buried gold, before hitting him with a baseball bat and knocking him into a grave.
