There was this game called Blazing Dragons on the PS1 that was crammed with good quotes. It was a point and click adventure with Monty Python like humour. A bit odd none of the quotes can be found on the internet though. A few I can remember a bit.
Flicker: I'm looking for Sir George's wife.
Gatekeeper: I'm afraid she is away for awhile. She and Sir George got into a fight. She had some big words, he had a big axe.
Flicker: When will she be back?
Gatekeeper: Well that depends... do you believe in reincarnation?
Gatekeeper: Do you know how hard it is for me to open this door? Stop wasting my time!
Once Flicker managed got into the castle he put on a fake Sir George costume that smells of dung. I refer to him as Fake Sir George.
Fake Sir George talking to the dog of Sir George who is quite scared: Don't worry boy. Today I'm nice!
Fake Sir George: Mervin! Give me status on... you know...the evil plan thingy.
Fake Sir George: Excellent work Mervin! Carry on, toodle pip, good show and all that.
Mervin: Your vote of confidence thrills me to no end Sire.
Wish I had the whole script of the game.
