A fancy man talking nonsense

Question

One day I met a fancy man, and tried to talk to him:

ME : Hello sir! How is your day?
HIM: Are you conversing with my person ?
ME : Yes I am, you seem like a very interesting person and I'd like to...
HIM: To my horror, I shall not authorize you to pursue in this course of action.
ME : Why not?
HIM: You will have to acquire a larger vessel.
ME : For what? I don't undestand...
HIM: Our dear language, oedipian fellow, are you able to converse in it?
ME : OK, now you're being rude... I think.
HIM: I reckon this is quite a large heap of excrement.
ME : I'm sorry, do you have a problem?
HIM: I witness individuals no longer breathing.
ME : I see...
HIM: Please greet my short acquaintance.
ME : There is no one else here. Or is this one of those "non-breathing people"?
HIM: I will bestow the man a proposal he won't be able to decline.
ME : He won't be able to accept it either, since he is inexistant.
HIM: You are unable to withstand the veracity.
ME : And can you tell me what is this "veracity"?
HIM: I relish the perfume of burning phosphorus at dawn.
ME : Well, now you're freaking me out. It was... nice to meet you sir, have a good day.
HIM: I shall wish the Strength to go along your person.
ME : Thank you, now go away from me.
HIM: I shall return promptly.
ME : Please don't.

What the hell was this all about?

Edit: I have looked this one up now, because it didn't quite match. There's "I'm sorry, Dave. I'm afraid I can't do that.", and a little later "I know that you and Frank were planning to disconnect me, and I'm afraid that's something I cannot allow to happen.". Neither matches exactly.
