If you want to have a romantic dinner at home then send your butler to bed to be alone with your guest. That is, of course, if you have enough money to afford a butler. Just send him to bed with the words go to bed, little father. Then have a little chitchat and wait for the clock to strike twelve.

Then go ahead with this dialogue (only works if you’re in Paris though):

“Do you hear that?”
“It’s twelve o’clock.”
“It’s midnight. Look at the clock. One hand has met the other hand. They kiss. Isn’t that wonderful?”
“That’s the way a clock works. What’s wonderful about it?”
“It’s midnight. One half of Paris is making love to the other half.”
“You merely feel you must put yourself in a romantic mood to add to your exhilaration.”
“I can’t possibly think of any better reason.”
“That’s false sentimentality.”

So, from which movie is this very romantic extract?
