Funniest thing you ever saw on The Simpsons

The best part about that episode was the cameo of Mr. Peabody & Sherman!
"QUIET YOU!"

 

Classic scene from the Astronaut episode, with Homer and Barney training. Barney drinks the celebratory non-alcoholic champagne and gets returns to his pre-training behavior. He flies aways and crashes on top of a the roof of a pillow factory and falls to the ground with a marshmallow truck runs him over. Homer celebrates with the sweetest 2 words in the English Language: "De-Fault"

 

Hank Scorpio! "But Homer, if on your way out you wanna kill somebody... it would really help me a lot..."
This one and the Monorail episode are my favorites.

 

The Hank Scorpio episode is probably my all time favorite episode. Albert Brooks is phenomenal as Hank. When I saw Albert was going to be in the Simpsons Movie I thought they were revisiting Hank. Of course he ended up doing a different character.

One of the funniest things about it is they actually got Shirley Bassey to do a bond style Scorpio theme over the closing credits!

 

Leonard Nimoy: "I think this vehicle can do at least Warp Five."
Mayor Quimby (interrupts) "And, ehhh.... may the force be with you."
Nimoy: (annoyed) "Do you even know who I am?"
Quimby: "I think so. Weren't you one of the Little Rascals?"

 

"SCORPIO! His twisted twin obsessions are his plot to rule the world and his employees' health!
He'll welcome you into his lair, like a nobleman welcomes his guest
With free dental care and a stock plan that helps you in-veeeeeeesssst!"

 

"Wow, former president James Taylor!"

 

Homer enters the Witness Protection Program:

Agent: "Remember, you are now Homer J. Thompson. So when I say, 'Hello, Mr. Thompson,' you smile and say 'Hello.' Ready? Hello, Mr. Thompson."
Homer: (blank stare)
Agent: "Let's try this again, when I say 'Hello Mr. Thompson,' and press down on your foot, you say 'Hello.' Okay? Got it? Hello, Mr. Thompson."
Homer (to other agent) "I think he's talking to you."

 

"Lisa, in this house, we obey the laws of thermodynamics!"

 

I’m sure it’s been posted elsewhere in this thread, but you reminded of the time Homer, trying to avoid jail time by going undercover after failing to pay his taxes, tells the IRS agent, “Can you pay me in cash, I’ve got a little tax problem”.

 

I'm Mr. Plough, that's the name
That name again is Mr. Plough

 

From that same episode...

Homer: "You can't send me to prison! They pee in a cup and throw it at you! I saw it in a movie!"
Agent: "You won't be seeing any prison movies where you're going... PRISON!"

 

You don't know how many times I've been in a meeting and I've wanted to go chase squirrels round a tree instead.

 

the scene where Bart writes on the back of Homers head and he spins around furiously trying to read it

 

I tried to find the part but it is when Ned Flanders is babysitting Bart and Lisa and they tell Ned they are not saved. Ned calls Reverend Lovejoy and says something like "simpsons kids... diddly.. are not saved, daddily, oh diddly diddly!" Then Lovejoy tells him he should join some other religion.

EDIT - found it!
It is towards the end of this clip but yeah I loved it

 

“You want the Mr. Plow who plows driveways. This is Tony Plow...you know, from Leave It To Beaver...yeah, they were g*y”.

 

this

 

FLANDERS: How do you silence that little voice that says "Think!".
HOMER: You mean Lisa?

About the funniest moment I can recall off the top of my head and that made me laugh out loud is when Homer is a paralyzed Spiderman and shoots a web out of his ass and nabs the special guest criminal.

 

Homer continuing to eat the spoiled submarine sandwich even after it's repeatedly made him sick.

 

Halloween episode.

Grampa runs into the room towards Bart with a hammer and stake yelling "kill the boy!"

Homer says: "how did you know Bart's become a vampire??"

Grampa says: "a vampire!!!" And runs out of the room.

I'm easily amused.

 

Oh and the one where the kids get taken away and put into foster care with the Flanders' and Ned says "Hidely ho neglecterinos." When they arrive.

 

Same with the free pound of shrimp.

"Hey, this shrimp smells funny!"
"Ok, two pounds."
"Woo Hoo!"
(Followed by ambulance siren.)

 

"So, to you, Mr. And Mrs. Erotic American

I bid... good day."
