Little John and Friar Tuck, sizeing each other up.
Little John: He's well named Friar Tuck. It would take half the deer in Sherwood Forest to fill that cabin.
Friar Tuck: And twice that to fill your empty head!
All the scenes with Much and Bess that aren't CMOH.
Little John winning the quarterstaff fight with Robin on the bridge.
Little John: (slams his staff onto Robins poor foot, Robin then starts dancing around on one foot) And here's your change! (waps Robin on the head with his staff)
Lady Kluck taking down the guards NFL-style to the tune of the USC fight song and "On Wisconsin".
Heck, the ENTIRE fight/chase scene.
Little John: Hey, who's driving this flying umbrella?!?
"Don't worry, sheriff, the safety's on Old Betsy"
"Criminently, now I know why your momma called ya Nutsy."
"I know my name! GET ON WITH IT!"
"Your traps just never work! And now look what you've done to your mother's castle!"
And the scene after that when Prince John screams and says, "Mommy," before he begins sucking his thumb again and then starts chasing Sir Hiss, trying to hit him with a stick that he was about to hit him with earlier before Hiss mentioned his mother.
Prince John talking in his sleep:
"Robin Hood?! I... get..."
[groaning] "Robin Hood, I.. I... I want..."
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.
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?
