Pinky: He isn't talking about Indulgences. Indulgences is the Medeival practise of buying your way out of Heaven, which m101 didn't even refer to...
Dave: You're giving the Anti-Pinky Faction a bad name!
Steve: Ah, I see we have a Dirk Gently fan in our midst...
I have never seen ghosts, but I do believe that they exist. This may seem to be in opposition to my generally Scientific way of thinking about things, but I haven't seen any believeable evidence either way, so I choose to believe the option that I would prefer. I would prefer that ghosts do exist, so that is what I believe.
Poltergeists, on the other hand, do not exist. They are just latent Psychokinetic abilities that become out of control during difficult times of one's life (e.g. Adolescence). That's what I think, anyway...
