"Daphne" in the berth, with the lady band members passing food around and a corkscrew's been brought. "Girls, keep it down! You'll wake up the neighbours downstairs, now Josephine... WATCH THAT CORKSCREW!"
Jerry dancing an ecstatic tango on the bed tells Joe about his engagment.
Joe: Jerry, listen to me! There are laws, there are conventions; it's just not done!
Jerry: Joe, this may be my last chance to marry a millionaire!
The reason Lemmon is shaking the maracas after each punchline was because the director knew the lines would be funny, and wanted to pause between the banter so people wouldn't laugh over the next lines.
Jerry: Oh no you don't! Osgood, I'm gonna level with you. We can't get married at all. Osgood: Why not? Jerry: Well, in the first place, I'm not a natural blonde. Osgood: Doesn't matter. Jerry: I smoke! I smoke all the time! Osgood: I don't care. Jerry: Well, I have a terrible past. For three years now, I've been living with a saxophone player. Osgood: I forgive you. Jerry:(Tragically) I can never have children! Osgood: We can adopt some. Jerry: But you don't understand, Osgood! (Jerry finally gives up and pulls off his wig) Jerry: Ohh... I'm a man! Osgood:Well...Nobody's perfect! (Jerry pauses and gives Osgood a perplexed look)
Even better, the original line was, "I know.", but sadly the censors made them change it.
If the movie was made today, the line might be something like, "Well, gay marriage isn't illegal everywhere".
