The producers halt the credits in order to get rid of the Swedish subtitlers... only to have the second team of credit-makers still obsess over moose being in the film. THAT team gets sacked, with a third team of credit-makers hired on from some South American firm... that quickly inserts llamas into the credits. Somehow, this is ignored... or more likely the producers just gave up at that point.
One last note, because the credit-makers were all sacked the ending credits didn't exist.
The very first scene after the credits. A sound of horses... followed by one guy pantomiming horse riding while another behind him claps coconut halves together.
The entire "Bring out your dead!" sequence...
"I'm not dead!" "You're not fooling anyone, you know." "I feeeeel happy!" *clonk*
And then the French dump shit all over him near the end. Literal shit.
In the scene with the monks hitting their faces with the tablets, there's one who's way too early. Watch him after and it's obvious the actor's trying not to screw up again by waiting for everyone else to hit first. Starts here at :22 on the right, second to last guy.
Dennis the peasant taking apart the legend of the Lady of the Lake and Excalibur, to the increasing annoyance of Arthur:
King Arthur: The Lady of the Lake, her arm clad in the purest shimmering samite held aloft Excalibur from the bosom of the water, signifying by divine providence that I, Arthur, was to carry Excalibur. THAT is why I am your king. Dennis: Listen, strange women lyin' in ponds distributin' swords is no basis for a system of government. Supreme executive power derives from a mandate from the masses, not from some farcical aquatic ceremony! King Arthur: Be quiet! Dennis: Oh, but you can't expect to wield supreme executive power just because some watery tart threw a sword at you! King Arthur: Shut up! Dennis: If I went 'round sayin' I was an emperor, just because some moistened bint had lobbed a scimitar at me, they'd put me away!
Right at that part, keep your eyes on Cleese; he gets this manic look on his face... no wonder the others were almost corpsing while filming this part. (That's why Eric Idle suddenly starts biting down on his scythe; he was that close to losing it entirely.)
God: "Oh, don't grovel! One thing I can't stand it's people groveling... AND DON'T APOLOGIZE!! Everytime I try to talk to someone it's 'Sorry this' and 'Forgive me that' and 'I'm not worthy'... WHAT ARE YOU DOING NOW!?
The failed attempt at entering the French castle in a "Trojan Rabbit", particularly Sir Bedvedere's reaction upon realising the problem (hint: he's supposed to be in the rabbit at the time). "I...uh... look, if we built this huge wooden badger..."
King Arthur: If he was dying, he wouldn't bother to carve "Aaaarrrgh"! He'd just say it! Brother Maynard: Well, that's what's written here. Sir Bedivere: Perhaps he was dictating. King Arthur: Oh, shut up!
All leading, of course, to the dramatic entrance of the legendary Black Beast of AAAAARRRRRRGGGHHH!
