I'd like to draw your attention to a game called "Fluxx" and the Monty Python version, here:

http://fluxxgames.com/

It's insane, and lots of fun.

I have no connection to the company and will receive no commission. Unfortunately.

(Zombie Fluxx is also very good.)

Wow... what a can of worms you've opened with THIS week's theme, Scott. The Python boys must have somewhere around ten thousand memorable dialogue moments to their credit!

To start things off, I'll keep it simple (yet no less hilarious)...

JAILER: Crucifixion?
MAN: Yes.
JAILER: Good. Out the door, line on the left, one cross each.

A classic.... (but then again, they all are)

Mr Barnard: What do you want?
Man: Well I was told outside that...
Mr Barnard: Don't give me that, you snotty faced heap of parrot droppings!
Man: What?
Mr Barnard: Shut your festering gob, you tit! Your type really makes me puke you vacuous, toffy-nosed, malodorous pervert!
Man: What? I came in here for an argument.
Mr Barnard: Oh, oh oh I'm sorry, this is "abuse'. You want Room 12-A just along the corridor.
Man: Oh sorry. Thank you very much, sorry, thank you.
Man: Stupid git.

The Black Knight scene (AKA "It's just a flesh wound!") was the most quoted thing around when I was in high school. It was before out time, but one of the guys discovered it and, before you knew it, all of the guys knew it all by heart and would break into it at the drop of a hat. Er, limb.

I liked the taunting Frenchman the best.

My favorite exchange from MP and the Holy Grail, King Arthur meets Dennis, the proto-anarcho-syndicalist.

ARTHUR: Old woman!
DENNIS: Man!
ARTHUR: Old Man, sorry. What knight live in that castle over there?
DENNIS: I'm thirty seven.
ARTHUR: What?
DENNIS: I'm thirty seven -- I'm not old!
ARTHUR: Well, I can't just call you `Man'.
DENNIS: Well, you could say `Dennis'.
ARTHUR: Well, I didn't know you were called `Dennis.'
DENNIS: Well, you didn't bother to find out, did you?
ARTHUR: I did say sorry about the `old woman,' but from the behind you looked--
DENNIS: What I object to is you automatically treat me like an inferior!
ARTHUR: Well, I AM king...
DENNIS: Oh king, eh, very nice. An' how'd you get that, eh? By
exploitin' the workers -- by 'angin' on to outdated imperialist dogma which perpetuates the economic an' social differences in our society! If there's ever going to be any progress--
