Do you realize that I work at home?....Well I work all the time, so never, never interrupt me..O.K. Not if there is a fire. Not even if you hear the sound of thud from myapartment and one week later there is a stench coming from my home that is so thick that you have to hold a hankie to face because you think you're gonna faint. Even then, don't knock. Or, if you're excited and you want to celebrate because some fudgepacker that you date got elected the first queer president of the United States, and he's going to have you down to Camp David,..And you want someone to celebrate the moment with.....Even then, don't knock. Not on this door...Not for any reason......Do you get me sweetheart? Melvin Udall in As Good As It Gets
My favorite monologue from that movie comes also from the same character. The cleaning lady from down the hall knocks at the door and ask Nickelson if he would look after the dog (I think) and then Nickelson replies (paraphrase): "Where do they teach people to talk like you? Go peddle your brand of crazy somewhere else; we're full up here."
