Funniest part of the movie?

I thought the funniest part of the movie was when Dyan Cannon and Charles Grodin realizae Leo Farnsworth is still alive right after they think they've killed him and Julia Farnsworth can't stop screaming. Cannon and Grodin are just BRILLIANT in this film.

The pained expression on the butler's face every time Joe is in a "costume" and asks..Do i play polo? Do I sail?...Not really, Sir...No Sir...So Funny.

For me, one of the funniest parts was after Joe talks to Betty. He returns home and the scene cuts to showing that Julia and Abbot in bed together (not surprising). Joe knocks on Julia's door. Julia knocks Abbot off the bed and he hides behind some curtains. Joe comes into the room and says:

Joe: Look, you don't love me. I don't love you. Let's get a divorce.
Julia: Really! I don't know what you're talking about!

Then, Joe makes it known that he knows Abbot is somewhere in the room, Joe asks him a question and after a brief pause Abbot answers and makes his presence known and Joe leaves the room.

Julia: You idiot! Why did you answer him?!
Abbot: His will is overpowering...

In the next scene, Joe throws his jacket on his bed and a screen glass (or whatever) comes down on the bed. He's surprised at first and then remembers that Julia and Abbot are trying to kill him.

Later, Abbot and Julia are in bed again certain that Joe is dead. Then, Joe goes upto Julia's room and shows the naughty couple that he is NOT dead and once again makes it known that he knows that Abbot and Julia are sleeping togther behind his back.

What really got to me was that Joe was trying to act normal despite discovering that his "wife" and personal secretary are being unfaithful to him and planning to murder him. ^^
Great movie. *sigh* Those were the good ol' days...

Oh, that's easy. At the end of one of the most ear-piercing screams ever uttered (by Dyan Cannon), it is innocently explained that 'Mrs. Farnsworth saw a mouse....not now, earlier...but she relives it!!'

It's one of those head-shaking, 'omigod-these-people-are-insane' kind of funny moments!!

I liked the part where Dyan Cannon said, "I should be cannonized." It was hilarious on a number of different levels.

When Vincent Gardenia had everyone in the livingroom together & he was questioning them, I think is one of the funniest moments in the movie. Especially the way Max acted.

"From now on, I don't want you to show me any more hats."

"The great Johnny Rocco, with Nora's spittle hanging from his face."

My favorite part is the line after he tells Dyan Cannon they are getting divorced.

Paraphrasing:
"I don't love you and you don't love me so let's get divorced."

She laughs, then says "Leo, I don't know what you're talking about."

Beatty throws up his hands and goes "Oh, come on. Yes you do."

The way he says that line always cracks me up. One of the few times I ever rewound a film and watched a joke twice because it cracked me up so much. That whole scene is priceless.
