Maude: Does the female form make you uncomfortable Mr. Lebowski?
Dude: Is that what this is a picture of?
Maude: In a sense yes. My art has been commended as being strongly vaginal, which bothers some men.
The word itself make some men uncomfortable.
VAGINA.
Dude: Oh, yeah?
Maude: Yes they don't like hearing it and find it difficult to say, whereas without batting an eye, a man will refer to his dick or his rod or his...johnson.
Dude: Johnson?
i like that one. there's also this one:
Maude: Do you like sex, Mr. Lebowski?
Dude: Excuse me?
Maude: Sex. The physical act of love. coitus. Do you like it?
Dude: I was talking about my rug.
Maude: You're not interested in sex?
Dude: You mean coitus?
Maude: I like it too. It's a male myth about feminists that we hate sex. It can be a natural, zesty enterprise. How ever there are some people, it is called satyriasis in men,
nymphonia in women, who engage it in it compulsively and without joy.
Dude: Oh, no.
Maude: Oh, yes Mr. Lebowski. These unfourtunate souls cannot love in the true sense of the word. Out mutual acquaintance Bunny is one of these.
Dude: Listen, Maude, I'm sorry if your stepmother is a nympho, but you know...
Those are my favorites. and the second one shows that the Dude is set on only one thing; his rug!
