There are two types of ghosts that linger on the plain of the living: evil types, who seek revenge in the form of haunting, and spirits who just won't give up, whether it be for love, food or denial of their ghostliness.
Unfortunately, many of the ghosts that fall into this latter category also ended up as "really f*cking annoying ghosts" (scientific term), a classification for paranormal beings that should just throw in the towel and crossover.
Take Casper, the "friendly ghost." Nice kid, sure, but his never-ending quest to be a normal boy and hook-up with a living girl is nonsense. Dude, I'm positive there are chicks in the afterlife, maybe even one who like bald guys!
