I'm sorry, but I just don't think the Stooges are funny. *ducks*

This is not an actual joke from a Stooge film...

Q: What college did the three stooges attend?
A: Why U!

This isn't an official joke either, but...

Where do the Stooges live?

Hey, Mo.

Larry: I don't see a single cow.
Curly: I don't see any married ones, either.

(from Sing a Song of Six Pants)
Moe: (after learning they're going to be forclosed upon) We're gonna be paupers ... paupers!!
Shemp: Are you kiddin'? ... We ain't even married!

I love the episodes that were filmed during WWII where Moe would pretend to be Hitler and deliver a barrage of German-sounding gibberish ending with "R-r-otten Skunk!"

Actually Moe was the dictator of Moronica.

(a train porter is caught in a window he was jumping out of running from a lion ... the lion is scratching him on his backside)
Porter: (screaming) Help! Help! I'm losing my mind!!

(from Wee Wee Monsieur)
Sultan: Find these intruders and bring them to me!
Nubian Guard: Yowza, Boss!

(from Ants in the Pantry)
Mouser: Any checks?
Secretary: No checks ... all bills.
Mouser: Bills, bills ... nothing but bills! This rat-catching business is going to the dogs! Where are those three loafers?
Secretary: They're in there, talking politics.
Mouser: Politics?
Secretary: Yeah, I just heard one of them say, "Let's have a new deal".

Moe: Anna Konda
Larry: Anna Konda
Curly: On account-a what?!?

"What are you doing?"
"We're shooting golfs!"

Curly: I was a pilot during the war.
Female: A pilot? How exiting!
Curly: Yeah, I'd take the potatoes from one corner of the room and pilot in the other.

(from Back from the Front)
Moe: We need to find some disguises ... if we're discovered, we're lost!
Curly: You're crazy! If we're discovered, we're found!

(from Rockin' Thru the Rockies)
Brave: This property belong to Escrow Indians ... no paleface allowed.
Curly: We ain't pale, we're sunboint!

Can't rmemeber the episode, but it was when some high society guy was trying to make gentlemen out of the stooges. A reading lesson from some lady had the line

The teacher: see a deer! Does the deer have any doe?

Curly: yeah....two bucks! nyuk! nyuk!

Curly:"My father died dancing....at the end of a rope!"
