Through the mist in medieval England is the sound of hoof-beats.  Horsemen are approaching!  Regaled in armor and accompanied by banners and porters, what a fine sight to see.  However, you quickly realize that there are no horses.  Are those coconuts?  Yep, they sure are.  "Monty Python and the Holy Grail" is unlike any movie you have ever seen before, and quite likely will ever see again (unless some fool attempts to do a remake).
