Well, around here in SW Ohio "Greetings and salutations’, "What’s your damage, Heather?!‘’ and “Well,fuck me with a chainsaw” were slipped into the conversations of many a Saturday night’s festivities 
How about “You ain’t seen nothing yet” from The Jazz Singer (1927)?
That’s a good one but it might be disqualified on a technicality. It was originally from a Jolson record released 8 years earlier (and 55 years before BTO 
)
The phrase was in use well before 1927. Here’s a use from 1876 and here’s one from 1895 and here’s one from 1920.
The actual line from The Jazz Singer…
“Wait a minute, wait a minute, you ain’t heard nothing yet.”
Heard, not seen, because until then movies were silent.
I do, maybe once or twice a year. So, around #50 on this list, for me — but legit.
Although the AFI’s list of 100 greatest movies quotes contains six from “Casablanca”, they do not include “I’m shocked, SHOCKED…” which seems to me to have and to see more everyday use than the others.
It might require more context than “here’s lookin’ at you, kid” and the others. But I think you’re correct that it gets a lot of use.
That is so fetch.
I had to look that up, because I’ve never once heard or read someone say that.
Just as Regina predicted.
“You’ll shoot your eye out, kid”
“Surely you’re joking!”
What movie invented that phrase?
Airplane?
Sliding Doors is a phrase I’ve seen used a lot over the last 25-odd years, as in ‘a real Sliding Doors moment’, where had something panned out slightly differently, the future could have been very different.
I’ve never once heard or read that phrase.
You must have missed the movie.
Today I learned that “Shut your pie hole” came from Christine by Stephen King. It was in the book and used in the movie.
From Crocodile Dundee:
“That’s not a […]. THIS is a […]!”
(Insert the appropriate noun.)
