YOINK!
I used to use Flanderisms all the time (“Okie-dokie-doo-diddly,” sometimes with a “neighbor” thrown in at the end for posterity), but a friend of mine got so annoyed with the habit that he took it upon himself to exert some discipline and make me kick it. He took the lock-ya-in-a-room-and-make-ya-smoke-a-whole-carton approach: over a period of a few weeks easily more than half of everything he said was appended with a surrealistic amount of “diddly-dum-skiddly-skee-dad-padoink-blurble-skerbalawala-hum-piddly-doo” ejaculations, all done in damnably pitch-perfect Flanderese. No matter what we did to try to get him to stop, he kept at it until nobody could even conceive of ever watching another Simpsons episode, let alone quote one.
I now live as a hermit in the Colorado mountains.
I’ll leave you to fill in the blanks.
this is paraphrased, so feel free to correct me.
“Ahhh, nothing like a monkey knife fight”
My workcenter runs the ship’s entertainment system, so sometimes in the shop we say “That ship is rebroadcasting ESPN with implied verbal permission instead of express written permission, or so the legend goes.”
When I make soup and it’s ready, I say “Good news, There’s enough gazpacho for everybody!”. They just roll their eyes.
Although I usually find myself quoting that show 50 times a day, the one line that I am just so impartial to, it’s become a habit…everytime I am in a parking lot and I am walking away from the car, I automatically say “remember, we’re in the Itchy lot”
Whenever anyone’s making a shopping list:
“Steak?”
“We can’t afford steak.”
“Steak?”
“All right, steak.”
“Shavin’ my sho-o-o-o-oulders… shavin’ my sho-o-o-o-oulders…”
“Cleaning my gun with the safety off, the safety off, the safety off… cleaning my gun with the ::BLAM::!!”
“Stealing, stealing, stealing a car for Moe… dum de dum de dum de dum, insurance fraud today…”
“Simpson… Homer Simpson… he’s the greatest guy in hi-stor-y! From the town of Springfield… he’s about to hit a chestnut tree… AAAAH!!! ::crash::”
And any of the other songs that Homer sings from time to time, such as the little ditty that goes on in his head just as Troy and Selma were about to get married.
Whenever I post off a competition entry, I say “Godspeed little doodle” as my good luck charm.
Get bent
So many glorious quotes - if only I could recite them all. Methinks “d’oh” and excellent have become firmly ensconced in pop culture. A few others I’ve used…
Person X: “In theory blah blah blah”
Me: “In theory, Communism works. In theory.”
I overused that one so much I stopped.
Homer, trapped in mountain cabin with Burns and hallucinating: “Stay back! I have powers… political powers!”
Sea Captain [paraphrase] “Yarrrr… 'tis no man. Tis a remorseless eating machine.”
Homer: “Lord, I know I shouldn’t eat thee…
Mmm, sacrilicious.”
Diamond Joe Quimby: “You can’t seriously want to ban alcohol! It tastes great! Makes women appear more attractive! And renders one virtually invulnerable to criticism.” (never used in context 
)

“I’m just going out to commit certain deeds.”
“Your ideas are intriguing, and I wish to subscribe to your newsletter.”
I’m also fond of “Choke on your lies!” even though I can’t remember if was definitely Homer who said it, or what episode it’s from.
When throwing something away, I sometimes use “Arrividerci, Vito!”
Which is usually, and inexplicably, followed by the line after it, “Boy, I was a fool to think anyone would want naked photos of Whoopi Goldberg.”
I like the drinks at the movie theater that are made of crushed ice and syrup. I think they are called Icees? Anyway, I always order “cherry squishies”. I’ve never had a counterperson misunderstand me, either.
Almost forgot this one:
I like my beer cold, my TV loud, and my homosexuals fuh-LAMING!
