Becky: "Is this an example of your bedside manner, doctor?"
Dr. Miles J. Bennell: "No, ma'am. That comes later."
Classic.
And then there is also,
Waiter: "Martinis?"
Dr. Bennell: "Make it two. Dry. Very Dry."
Miles (upon hearing they will be reborn into a world where everyone is the same): "I dont want any part of it"
Dr. Dan Kaufman: "Youre forgetting something, Miles."
Miles Bennell: "Whats that?"
Dr. Dan Kaufman: "You have no choice."
Also this little gem:
Miles J. Bennell: "Well, you win. Pick up the marbles."
