I've heard from many sources that the ending to Monty Python and the Holy Grail (where it abruptly ends just before an invasion on the French castle, due to the police arriving to arrest the cast) was put in at the last moment because they were essentially out of money. This is about when the quest for the Holy Grail became the main plot thread; at that stage it was to be found in Harrods (because they have everything).
This doesn't really strike me as true, given the foreshadowing that built up to it (the historian scenes). If so, what was the original ending supposed to be? The historian sequences were added at some point during the writing, well after the first draft.

Why do think I have this outrageous accent, you silly king! I blow my nose at you, so-called Arthur-king, you and all your silly English knnnniggets.
ARTHUR: If you will not show us the Grail, we shall take your castle by force! ---Go and boil your bottoms, sons of a silly person.
GUARD: I don't want to talk to you no more, you empty headed animal food trough wiper! GUARD: No, now go away or I shall taunt you a second time-a!
