Made even funnier by Robin's bemused reaction when he starts laughing hysterically in his sleep, due to Sir Hiss' tongue tickling the bottom of his foot...who he then involuntarily kicks. The look Robin gave John for the strange noises he was making in his sleep prior to this can only be matched by Hiss' when he wakes up and sees John's foot nearby, post-kicking.
After Robin gets the bag of money from under John's pillow, John starts crying like a baby and sucks his thumb. Causing Sir Hiss to wake up with a hilarious look on his. Robin gets the last money bag from between John's arm, which removed John's thumb from his mouth. Still sleeping, he tries to reach for his thumb. Robin takes one look at him, then gets the bag, sending the thumb right back into John's mouth.
Drunk Sir Hiss
Prince John: Hiss! You're never around when I need you!
Sir Hiss:(from inside of the beer barrel) Coming, coming. (laughs) For I'm a jolly good fellow, for I'm a jolly good fellow. (Prince John uncorks the barrel and Sir Hiss comes out) Oh, there you are, old boy! PJ, you won't believe this, but the stork was really Robin Hood!
Prince John: Robin Hood? (Sir Hiss nods as Prince John begins to laugh, until he screams and strangles Sir Hiss, before tying him in knots on a pole) Get out of that if you can.
The way Little John introduces himself as 'Sir Reginald, Duke of Chutney' to Prince John. He's basically being as big a ham as the prince can be, and milking it for all it's worth.
Four words: "GET OUTTA MY CHURCH!"
The whole bit with Skippy and his friends sneaking into the castle to get his lost arrow, spying on Lady Kluck ("As your lady-in-waiting—I'm waiting!") and Maid Marian (very amused by Lady Kluck's attempts to get the shuttlecock out of her bodice), and culminating in Skippy's pretend duel with Kluck as Prince John. Her over-the-top villainy, melodramatic "death scene", and spot-on impression of the Momma's Boy is absolutely hilarious. Honorable mention goes to "dead" Kluck whispering to Skippy to take his lady fair to Sherwood Forest, followed by Skippy dragging Marian into the bushes calling her "lady fair" ("Oh Robin, you're so impetuous!") and, when he won't give a kiss to her, Marian kissing him (on the cheek of course).
"Sheriff, I make the rules, and since I'm head man... (to Little John, who is threatening him with a dagger) ...not so hard, you mean thing... (Little John thrusts the dagger in deeper) ...LET HIM GO, FOR HEAVEN SAKES! LET! HIM! GO!"
At the very beginning of the climax, Prince John wakes up to Hiss holding onto Robin's rope and carrying him and his bed through his room and going off the side of his balcony window. That must have been one rude awakening.
Then when he sees the villagers getting away with his gold, he calls upon the rhino guards to head toward the jail, only to realize he's right at the jail.
Prince John: Rhinos, halt! STOP! DESIST!(rhinos crash into the gate and through the back wall with P.J. in tow)
Robin ambushes the Sheriff in his own carriage to try and intimidate him, only to find the Sheriff has gotten a bit bored with the routine. "Oh, not now, Locksley." When he suggests he means business this time, the Sheriff just kicks him out.
When the Sheriff is about to have Roy's mother executed, Roy screams: "You'll go to hell for this!" The Sheriff looks bemused as he says: "What? Just for this?"
After Guy is held captive by the outlaws, Marian tells the Sheriff that they're willing to give him up in exchange for Djaq. When he seems reluctant, she reminds him that Guy is his friend, leading to this:
Sheriff: "We are talking about the same Guy? I mean, I've barely noticed he was missing."
When Kate gets hit in the stomach with a dagger, collapses to the ground, and nobody notices her lying there for a good ten minutes. What. That wasn't meant to be funny?
