I still have one out there:
“Some guys think crackpipe burns are sexy on women!”
Also:
“Nobody’s perfect!”
“I was born lucky! Born with a veil, and that’s sho’nuff lucky!”
The guy at the gas pump, he’s got a lot of soul
He sings “Merry Christmas” to ya just like Nat King Cole.
And he makes up his own tunes right on the spot
About whitewalls and windshields and this job he’s got.
…show me the wayyyyyyyy to Barangrill
That’s from a Spider Robinson story “By Any Other Name” that he expanded to a novel of which I forgot the name. But I think its: “I hadn’t meant to shoot the cat.”
Here’s some:
“WET SLAPPITY OF DOOM!”
“They went to bed quite early and slept soundly until daylight, when they were awakened by the crowing of a green cock that lived in the back yard of the Palace, and the cackling of a hen that had laid a green egg.”
Nope.
Bravo. After Bugs says it the native goes wild at which point Bugs says to the audience “Wha’d I say? Wha’d I say?”
Danny Kaye in The Court Jester:
Made it, Ma! Top of the world!
James Cagney’s last line, White Heat
I am a mere member of the generation.
I just learned in another forum that Ipana toothpaste is available again. Alas, John and Sonny are no longer around to enjoy it.
Someone had the quote “nobody’s perfect” as a stumper; I believe that’s the last line of the movie “Some Like it hot”
You are correct! Oswald (Joe E. Brown) says it to Jack Lemmon after Lemmon tells him that he (Lemmon) is a man rather than the woman he’s dressed as.
The quote:
“Nice shoes. You make those in prison?”
is not (as I misremembered) from the movie Fletch.
It is, in fact, said by Bill Murray in a biographical sketch about him in Roy Blount Jr.'s book Now Where Were We?
Shit. And that was such a Fletch kind of thing to say, too.
Shut the fuck up, Swan. SWAN! SHUT - THE FUCK - UP!!
The poster was Johnny LA.
Nobody tried to guess mine from page 3. If it’s too difficult I could give a hint…
“Leaning over your fortieth masterpiece…
You must have loved the color of these violins”
“My dear Norman, why is it that so many suppose that souls are of less interest to us than to our adversaries ? Why should not one side strive for a worthy one as well as the other ? I am not a demon, nor is this hell”
“They believe I am a witch. They’re wrong…I think.”
“There were one hundred planets forming a wheel, nearly touching one another on two sides, with Earth sixteen globes past the smelly one in one direction and eighty three past it in the opposite direction.”
Those look like Terry Pratchett quotes. Especially the second one. The only shred of doubt I have is that his quotes wouldn’t be considered “obscure” on this board :).
From TV:
“They’re all the rage in Trenton, New Jersey.”
From Film:
“Have you checked the children?”
From Music:
“Why, even Dracula will be there!”
The Shaggs!
Not even close. 
The author involved is more obscure, for one. Good, I think but obscure.
Oops. Make that “authors involved are more obscure”; each quote is from a different one.
