"You're the only one that still quotes lines from Bugs Bunny"

Consequences, schmonsequences. As long as I’m rich.

In addition to many already mentioned:

…rats, bats, goats, stoats, and old gnus… but especially RABBITS!

The Illudium Q-36 Explosive Space Modulator! That Earth creature must have stolen it!

Why for you bury me in the cold, cold ground?

Thanks everyone! I’ll print this out and show it to her.

Terrifel, sorry about the snottiness.

“Rock…falling…what…should…I…do?” - Wile E entering that question into his computer, always reminds me of doing a Google Search. That scene may have sparked my interest in computers.

I use just about all of those, but especially the last one (although a bit modified). I use it when I’m washing my daughter’s hair; it has become its own little ritual:

Me: *It must be so iiinnnnnteresting being a Jessalyn. You must meet so many iiinnnnteresting people. My . . . *

Her: . . . stars!
I also use:

Yoicks! And away!
Hmm? Prithee? Hmmm?

And, upon preview, pretty much every one that others have already posted.

“That dog’s as subtle as a hand grenade in a barrrel of oatmeal.” Foghorn Leghorn

A good one from Tweety …

My po’ wittle cwanium!

Whenever someone asks if I have something, as I’m looking for it I keep saying,

“Have I got brass knuckles! Have I got brass knuckles!! Have I got brass knuckles?”

In regards to Daffy’s quote, “Down, down, down! Go, go, go! Mine, mine, mine! I’m rich! I’m wealthy! I’m a happy miser!” Is that what he says? I always heard the end as something like, “I’m getting my desserts…”

Did he ever actually say this in a regular cartoon? I only remember it from Roger Rabbit (and it wasn’t Mel Blanc doing Sam in that).

In addition to many others already mentioned:

“Pick up pie!”

“Oh, she was an acrobat’s daughter. She swung by her teeth from a noose. Then one matinee, her bridgework gave way and she flew through the air like a goose!”

When my sisters and I get into a hot tub, we all wiggle down into the water and say, “OOH! Ahhhh!”

“Nothing could be feener than to be in Caroleener in the mo-o-o-o-o-o-orNINK!” I also often do the scat singing that Daffy does in that one.

I frequently make that series of sounds that Bugs makes in the gremlin episode, when the plane is in free fall and he’s turning various colors, including plaid.

And I sometimes do the weeping to the tune of “Traumerei.”

BTW, what’s the name of the Bugs Bunny cartoon where he’s matching wits with the highway construction chief who wants to put a bypass right where Bugs’s rabbit hole is? I remember the chief blasts a moat around the entrance and pours concrete over it, but Bugs deflects the concrete with an umbrella and is left with a chimney-like “hole.”

And the one with Yosemite Sam as a sailing-ship captain, and Bugs as his sole crewmember.

No Parking Hare

Mutiny On The Bunny

Both of them have an ad before the cartoon, but it’s short.

Great horny toadies!

Bless you, jayjay!

When I visit my Dad up Nawth, the first words I say to him are “I gotta burn muh boots! They touched Yankee soil!”.

“You been eatin’ onions!”.

The best part comes after that, when the A-Snowman is fiercely petting Daffy and Daffy says

“Stop that. You’re hurting me.”

Or Black Jack Shellaq on top of the metal dam

“Thees rabbit ees sick. Sick, sick sick.”

I’ve been using the “Isn’t that innnnnnteresting?” line (from the Monster-in-the-Castle episode) with my 10-year old daughter for years. She and I just saw the cartoon for the first time together a few months ago. Now she knows where it comes from, and hasn’t stopped using it since.

And so it goes. From father to daughter.

Dragons is soooo stupid!

From “Hillbilly Hare”. Along with “The Rabbit of Seville”, by far and away my two favorite episodes.

Things haven’t been the same without you. Although they have been eerily similar.

Is this trip really necessary?

“I’m Riff-Raff Sam – the riffiest riff to ever riff a raff!”

“Whoa, camel!” (BASH!) “When I say whoa, I mean whoa!”

(from “Birds Anonymous,” when Sylvester turns on the TV to get his mind off Tweety)
“Af-ater basting, you’ll find that your bird is a goooooolden brown. Every succulent morsel willa simply melta inna your mouth!”

“Fifty thousand kronkites to the first man to climb the Shmatterhorn!” (And the Bad Swiss Band that goes along with it.)
