i just got done watching Ghostbusters for like, the hundredth time this week. i'm not sure why, but everytime i watch it, i have a new favorite part. but my all-time favorite part is where rick moranis gets possed and talks to the horse:

Louis: I am the Keymaster! The Destructor will come, the Traveler! The Destroyer! Gatekeeper! (he approaches a horse on a wagon) I am Vince. Vince Clortho, Keymaster of Gozer, Volguus Zildrohar, Lord of the Sebouillia. Are you the Gatekeeper?Wait for the sign, and our prisoners will be released. (runs off, yelling back to the coachman.) You will perish in flame! Soon as I find the Gatekeeper!
