"We're men! We're men in tights!/We roam around the forest looking for fights!/We're men! We're men in tiiiights!/We rob from the rich and give to the poor, that's right!"
Interestingly, that's a recycled melody from History of the World Part I, namely the "Jews in Space" preview at the end that's pretty funny in and of itself.
Don't forget the can-can part. Yes, really.
Not to mention Blinkin continually getting his steps wrong and punching the people standing next to him.
"I CAN SEE!"* wham* ".....nope. I guess I was wrong."
In that same scene:
Robin: Blinkin, what are you doing? Blinkin: Guessing? I.. guess no one's coming? Robin: Get down from there! Twit. Blinkin: I... guess there's a ladder around here somewhere... (feels around and falls out of treehouse)
Atchoo: ".....hey, Rob, maybe we should take the dummies into battle."
Robin: "Ha!" (pauses, frowns, and starts pondering seriously)
The Running Gag about the Sheriff of Rottingham's dyslexia, especially when he flips out over the killing of the wild boar, um, pig.
"ENOUGH! KING ILLEGAL FOREST! TO PIG WILD! KILL IN IT A IS!"
And other instances:
"Over that boy hand!"
"He DEERED to kill a king's DARE!....Dared...to kill a king's deer."
''"I'LL PAY FOR THIS!....YOU'LL PAY FOR THIS!" Made even better by Ahchoo nodding and grinning after the first line.
"My liege! Struckey has loxxed again!"
The catapult scene.
Sheriff of Rottingham: This is a stealth catapult, we've been working on it secretly for months. It can hurl one of these heavy boulders undetected, over a hundred yards, completely destroying anything in its path.
Prince John: Wow! How's it work?
Sheriff of Rottingham: It's rather simple. You get one of these heavy boulders, put it here where I'm sitting, and then pull on that lever.
Prince John: Like this? * Pulls lever, sending the Sheriff flying*
Latrine: * Praying by her bed* Oh dear Lord, if you see fit to send me my one true love... * The Sheriff crashes through the roof into her room. Looks up and says:* Thank you!
"SHUT UP, YOU BLOODY FOOLS!"
Da daaaaaaaaaaaaah, dadadadadadaaaaaaaaaaaaaaah, dadadadadada-da-da, dada-da-DAAAAAAAAAAAAAAAAAAAAAAAAAH!
"Now you've really pissed me off!" "Man, if I were that close to a horses wiener I'd be worried about getting pissed on!"
"Mind the big rocks!"
You haven't seen the last of us! [arrows pin Mook to tree] You've seen the last of us.
From the opening:
Villager: There must be another way of doing the credits!
Fireman: That's right! Everytime the do a Robin Hood movie they burn our village down!
(flaming arrows hit a rooftop, and flaming text appears showing who the movie is being directed by)
Villagers: LEAVE US ALONE, MEL BROOKS!
Rabbi Tuckman hawking circumcision to an ignorant Merry Men, stating "the ladies love it". Bonus points to Little John who responds, "I'll take two!" Once he finds out what it is he quickly blurts "...I change my mind."
