Not animated, but from The Far Side…
“Blah, blah, blah Ginger.”
“Say your prayers, varmint! I’ma gonna BLAST ya!”
“Get in the car, boid!” (some thugs were executing a poorly-considered caper to kidnap Tweetie-Bird)
My buddy and I have made a fine art of quoting a one-word line from The Flintstones over and over. Whenever one of us has done anything the least bit disappointing, such as not having seen a certain movie or not having tried a certain drink, the other will stand, extend a pointed finger toward the door, and bellow, “Ouuuuttt!”
Nearly every line of The Emperor’s New Groove:
These are my best shoes.
Why do we even have that lever?
We’re just going to be sitting around talking about how much we love each other!
And I never liked your spinach puffs. Never!
Yay, I’m a llama again! …wait.
Does it have to be those words exactly?
We both could have been spared your little “Kiss of Life”.
…not even on your birthday.
How long has that been there?
Don’t you say a word.
And many more, I’ll just stop there. Also some goodies from Spongebob:
I think I’ll eat it now!
They were white when I bought them.
Could you play a little… better?
Am I a pretty girl?
Weenie Hut Junior?!
That’s unpossible.
I am so smart. S. M. R. T.
My cat’s breath smells like cat food.
oooh! I had forgotten:
“What’s a diorama?”
and
“I’m Idaho!”
“I was a little too smart for him. Aye-yup!” ~ Binky Buzzard as an aside, talking about Bugs Bunny.
“He’s got a lot upstairs. No brains, just an empty lot.” - Baba Looey talking about Quick Draw McGraw.
50,000 Cronkites!
(whimpering): “I’ve had this ice cream bar since I was a child!”
My favorites are Cronk saying “Riiiiiight…” and Cuzco saying “No touchy!!” right before getting punched.
Me too. It’s because we’ve been hypnotized.
“I like him. He’s silly.”
“Shh. Be vewy vewy quiet.”
“You’re dethhhhhhhpicable.”
When making presentations to business groups, I’ve used a Boris Badenov bit from Rocky & Bullwinkle?
After laying out the requirements/challenges, I say:
“You ask if I got plan? Boris always got plan. Don’t always work, but I always got one.”
(Worked a lot better in the 90’s than it does today. Too many youngun’s who never learned the classics.)
Whenever one of us doesn’t want to do something my husband or I will say “No. Nooo.” in Consuela’s voice from Family Guy.
Penfold, shush.
Si, Barone!
“Are ya gonna come quietly or do I have to muss ya up!”
“We’re headed for outer space, Fred!”
“Let that be a lesson for you, Fred!”
And every once in a while, I’ll do the Super Chicken Cluck (at 6:17).
“We all have our little idiosyncrasies, Mrs. Jones.” Shot of psychiatrist sitting behind desk talking to patient. Viewer can see he is wearing nothing below the waist.
My husband’s:
“Ethel, I really wish you wouldn’t do that.” Husband and wife in car at stop sign. She is giving the finger to a gang of bikers.
though maybe
“That’s a joke, ah say, that’s a joke, son.”
another cartoon element borrowed from old time radio. in this case Foghorn Leghorn got it from Senator Claghorn on The Fred Allen Show,.
Hmm. I remember it as “exit, stage left!” One of us was watching in a mirror.
Others:
Good grief, Penfold.
From a R&B ad, not the regular show: “Never underestimate the power of a shnook.”
Yeah, it’s amazing how the words of The Emperor’s New Groove so often apply in everyday life. 
Any time I find change on the ground, I can’t help channeling Daffy Duck. “I’m rich! I’m rich! I’m faaaabously wealthy!”
Prepping veggies for a stew? “Hassan CHOP!”
