"That's tacky. That's
REALLY
tacky"

The look on Maggie Smith's face when her husband explains why some people might want a naked corpse, followed bywith amused disgust"How TACKY."

Ello,ello! I am saying ello, ello!

as someone who looks very young for their age.
How do I look so young? Its perfectly simple, complete vegetable diet, 12 hours sleep a night, and lots and lots of makeup

If I am ever caught in possession of some sort of lurid pornographic material, and on being asked why I had said material, saying this in my defence:
Suspects.always looking for suspects.
"Someone has been tampering with Hank's memories."

I love all these quotes and use a bunch of them but after 7 pages no one said one my favorites, "As you can seeI can see". IMO that one can be used easily when pointing out sarcastically that you arent blind

"I'm not a Frenchy. I'm a Belgie."

this I use.often
How do I look so young? Twelve hours sleep a night, a complete vegetable diet, and lots and
lots
of make-up.

Next time someone calls you on the phone, try answering by saying HELLO. The results will be hilarious. Think of the look on the face of the caller who hears you respond with HELLO. I'm totally guffawing now just imagining it. OMG, I think I wet myself.

I just read through this entire thread and was amazed that no one mentioned Dora telling the maid to come in before you did.

I like this bit of dialog (probably not verbatim):
After the clock has struck 12, there's a knock at the door.
Dora Charleston: It's probably the maid. Come in.
Dick Charleston: Darling, the poor woman is stone deaf.
Dora Charleston: Sorry, I forgot. (yelling) COME IN!
I love Dick Charleston's reaction to her yelling.
Other quotes:
Willie Wang: Who do you think the killer is, Pop?
Sidney Wang: Must sleep on it; will know in morning.
Willie Wang: What if you don't wake up?
Sidney Wang: Then you did it. Go sleep please.
Willie Wang: I don't hear nothin'. What do you hear?
Sidney Wang: Double negative and dog.
Twain: That drives me crazy.
Diamond: Sounds like a short ride to me.
I like that line because it's similar to what I've always told people when they use that phrase. Usually when someone says something is driving them crazy, I'll respond with "That's walking distance."
Dick Charleston: A blind butler.
Dora Charleston: Don't let him park the car, Dickie.
Sidney Wang hears a dog barking:
Bensonmum: That's only the cat.
Sidney Wang: That cat? You feed cat dog food?
Bensonmum: Mr. Twain had him fixed and he didn't wanted to be.
Sidney Wang inspecting the dead butler.
Sidney Wang: No pulse, no heatbeat. If condition does not change, this man, he dead.
Save the whales; collect the whole set.

I would love to blurt out "SHOOOOOOOOEEEES!"
My ex husband's name is Richard. I used to refer to him as my Dickie.
"So shines a good deed in a weary world."

Its a long time since I saw it, but I used to love it and watched it a lot. There are certain lines that stick in the mind. (I may not have them all word perfect, but like I say its been years. I will have the important bits right :).
"Oh Dickie, thats old news!"
"My kid brother went the same way That boy woulda been 63 on Tuesday."
"Sam why /do/ you always keep those muscle man books in your desk drawer?"
"Suspects baby. Always lookin for suspects."
"I'm not a Frenchy. I'm a Belgy"
"I prefer to be called Rita!"
Then there's the great moment when they pour the wine on the table and it turns out to be acid and burns the table-cloth. They're all congratulating whoever it was who guessed this, when Milo calmly says 'Cheers' and drinks his wine, and then explains to the shocked group that he knew that his glass would be OK.. and then collapses with a groan. Brilliant timing from Mr Coco here. Its so predictable: he is being so smug that you just KNOW he is going to collapse any second. And yet when he actually does, its still hilarious. :)) That's great comic acting right there.

"Maybe I should go alone"

• Quint, Jaws.

"What DOES he mean, Miss Skeffigton?"
"I'll tell you later it's disgusting."

"you look like number 2, know what i mean?"

Wang: "It is late and my eyes are getting tired."
Diamond: "I thought they always looked like that."
Tess reprimands him for the racial slur. I can't remember what she says.
Diamond: "You're right. I'm sorry slanty."
Diamond: "Why don't you roll her wheelchair down the driveway. We got business here."
Diamond: "You pick with my nits you won't have any nits to pick with."
Tess: "Sam you're spitting on the nurse."
I don't remember what he says after that but it was some sort of backhanded apology.
Peter Falk got the best lines in this movie.
