I can't believe you guys, of all people, haven't mentioned the waffle bart stuck to the ceiling that Homer thought was god...

Marge: "Homer, that's not God, it's just a waffle stuck to the ceiling"
<knocks it down with a broomstick>
<Homer picks it up>
Homer: " I know I should not eat thee..."
<eats it anyway>
"Mmmm....sacrelicious"

Or, for that matter, "Mmmmmm....forbidden donut..."

My favorite Homer moment is when Homer goes to Hell, and Satan has him hooked up to a donut force-feeding machine that stuffs about a dozen into his face at a time, and each time, Homer makes yummy noises, opens his mouth and says "more...mmmpfff...more...mmmpfff...more".

Mr. Burns doing the take-off of "Be Our Guest" from "Beauty and the Beast" wherein he musically lauds his animal-skin wardrobe is also quite fine.

I remember now, the very best is when Homer eats the insanity peppers and goes on an insanity pepper trip, off into the desert where he gets help from Johnny Cash.

I agree w/spode... "See My Vest" is brilliant.

Tubthumping (Homer's version)

I get knocked down
I get knocked down again
You're never gonna knock me down.

I take a whisky drink,
I take a chocolate drink,
And when I have to pee,
I use the kitchen sink.
I sing the song that reminds me I'm a urinating guy.

ralphie definitely gets the best one-liners

re: tommaco, "This tastes like grandma"

crowd booing mr burns: "BOOOO, BOOOOO, BOOOO"
mr burns: "Smithers, are these people booing me?!"
Smithers: " Uh, No, sir, I believe they are saying BOO-urns"
Mr Burns to crowd: " Are you people saying 'Boo, or BOo-urns?'"
Crowd: "BOOOOO!"
Moleman: " I was saying 'Boo-urns'"

the simpsons ROCK.

64 slices of american cheese...64...63......2.......wannnnn.

The entire Bobo episode is really good. Wow, there are so many hilarious moments running through my head right now from other episodes, it's impossible to name them all. I'll say it again, "mmm, floor pie"

we could have a thread of just the *funny things that follow MMMMMMMMMMmmmmmmmm........

that right there is a testament to how much impact the show has had. The mmmm thing has become a recognized verbal device in everyday conversation.

*all time best would have to be "pointy"

Homer: "why, oh why, did i squish that fish?"

time traveling toaster episode.

The episode where Lisa gets braces, and Homer is elected presidet of the union, is the best Simpsons episode ever: "Last Exit To Springfield"

Later in the episode, Lisa is getting her school picture taken, and doesn't want to smile because of her hideous braces:
If I pasted all the great lines from that episode, it would be just about the entire script. And I think a close second on best episode ever if "You Only Move Twice," where Homer gets a job working for the super-villain Scorpio.

I need to start watching the Simpsons again... My anti-TV habits have resulted in not seeing an episode in months.

Damnitall, that's my favorite quote!

Mmmmmm. Invisible Cola...

And anything from "Simpsons Hit & Run" -- Smashy, smashy!

- Pie

"oh that? that's german, for Die, Bart, Die."

"well, no one who speaks german could be evil."

How about ... the episode where Homer tries to win back Lisa by buying her a pony. This moment always makes me laugh so hard for no apparent reason.

[7:59 am: Homer walks into bedroom after working the graveyard shift at the Quik-E Mart]
Homer: Must ... sleeep ...
Marge: *grumbles*
[8 am: Alarm sounds]
Homer: Time to go to werrk ...

And then he falls asleep in the car, and hits the steering wheel to deploy the airbag and uses it as a pillow. FUCKING HILARIOUS.

Oh, there are so many ...

From the "April Fool's" Episode:

In the flashback, where the origin of April Fool's is discussed, and the early Christian Flanders come to visit the late Pagan Simpsons ... "Heidiliho Pagans! We've come to bring you some ram's blood for your godless ceremonies."

Then, of course, there is the moment of insight in "Homer Gets Fat" where Homer and Bart go to visit Dr Nick (who, incidentally, sounds exactly like an Emergency Room Physician I deal with) and he's explaining to Homer the rationale behind choosing foods that will help him meet his goal of going on disability for being fat ... "And remember, if you're not sure about something, rub it against a piece of paper.
If the paper turns clear, it's your window to weight gain"

The time travelling toaster episode is my fave too.
