What's your spookiest renovating experience? Anyone ever work on a haunted house?

The spookiest renovation we have ever completed was in Southern Cal. The homeowner wanted to paint all of his interior walls black so that an artist could come in after and paint glow in the dark ghosts on the walls for a haunted house. We completed the project and the crew came back to visit the home on Halloween. I must say that Universal Studios does not compare to the eerie and scary feelings of this home that day.
