Every time Schultz introduces his horse Fritz, who always obediently neighs and bows his head in response.
During Schultz's Establishing Character Moment scene he absentmindedly asks one of the slaves to hold his gun while he fumbles with other things. The slave's face when he's handed a loaded weapon is priceless.
He goes on to ask the slave to raise the lantern attached to the gun up a little higher so he can see, resulting in the barrel pointing directly at his head.
The giant tooth on a spring atop Schultz's wagon. Funny when you first see it, even funnier when they return to town, bouncing away. Look at it go!
First there's this gem as Schultz and Django walk into the saloon:
Dr. King Schultz: Good morning, innkeeper! [The bartender is standing on a chair, changing a candle in the chandelier] Two beers for two weary travelers.
Saloon Keeper Pete: It's still a bit early. We won't be open for another hour. By then, we'll be servin' breakfast. [turns around and immediately recoils upon seeing Django] Oh, shit! Woh! Woh! Woh! Woh! What the hell do you think you're doing, boy?! Get that nigger out of here! [Schultz stares at Pete]
[Cuts to the bartender bursting out of the saloon, running for his life]
Saloon Keeper Pete: Help! Help!
Dr. King Schultz:[comes out the front doors] Innkeeper! Remember, get the Sheriff, not the Marshal!
Saloon Keeper Peter: Sheriff! Sheriff! [Schultz walks back into the saloon]
Dr. King Schultz: Alas. Now we must act as our own bartender.
At the end of Schultz's conversation as he is setting some terms for Django to agree to with regards to the Brittle brothers:
Dr. King Schultz: I hear at least two of them are overseeing up in Gatlinburg, but I don't know where. That means we visit every plantation in Gatlinburg till we find them. And when we find them, you point them out, and I kill them. You do that, I agree to give you your freedom, twenty-five dollars per Brittle brother, that's seventy-five dollars...[notices the Sheriff approaching and smiles]...and as if on cue, here comes the Sheriff.
[The sheriff comes in, carrying a shotgun in his right hand]
Sheriff Bill Sharp: Okay, boys! Fun's over. Come on out.
[The sheriff walks out through the front doors, where we see that a group of townspeople have assembled, watching him]
Sheriff Bill Sharp: Alright, folks, calm down! Go about your business. [levels shotgun at the doors] These jokers will be gone soon. [Schultz and Django come outside] Now, why y'all wanna come into my town and start trouble, and...scare all these nice people? [Schultz walks towards the sheriff and stretches his right hand out as if to shake the sheriff's hand] You ain't got nothing better to do than to come into Bill Sharp's town and show your ass!
[A small Derringer promptly pops up in Schultz's right hand and he shoots the Sheriff in the stomach. The sheriff drops his shotgun and falls on his back, clutching the bullet wound. The assembled crowd stands there, dumbstruck]
Everything Schultz does, really, being something of a Heroic Comedic Sociopath. While he cold bloodedly murders people, the offhand and cheerful fashion in which he does so is utterly hilarious.
Django's first choice of clothes as a free man: a royal-blue coat with matching knee-breeches (tied off with blue ribbons), buckled shoes, and a very large, lacy bow tie. It comes off as an 1850s-vintage pimp suit.
Heck, it's more like 1750s. Apart from the deeper blue color and the big cravat, it's almost identical to ''The Blue Boy''. Django is even visible in a reflection in a nearly identical pose...
The film's costume designer admitted that she had slipped Tarantino a copy of The Blue Boy, leading to the final design.
Lampshaded by the slave-girl on Big Daddy's plantation: "You mean you wanna dress like that?!"
Django's expression when Schultz tells him he can pick out his own outfit. It just screams "Oh, I'll be taking full advantage of this."
I can't be the only one who found his Badass pose in the outfit as he calls out "JOHN BRITTLE!" coupled with his Determinator expression hilarious. Made even better a few seconds later when he grabs the whip and starts whipping the white farm hand!
Bait and Switch: The slave girl at Big Daddy's plantation pointing out the smoke-house "Where Big Daddy hangs all the critters he kills ... poor little squirrels."
Schultz rushes in just after Django shoots down Little Raj and Big John Brittle:
Spencer 'Big Daddy' Bennett: Now, unless they start shootin' first, nobody shoot 'em. That's way too simple for these jokers. We're gonna whup that nigger lover to death. And I'm gonna personally strip and clip that garboon myself.
[he puts on his mask]
Spencer 'Big Daddy' Bennett: Damn, I can't see fuckin' shit outta this thing!
Bag Head #1: We ready or what?
Spencer 'Big Daddy' Bennett: Aw, hold on, I'm fuckin' with my eye holes. [he rips the material around his eye hole] Oh. Oh, shit. I just made it worse. [he takes off his mask]
Tennessee Redfish: Who made this goddamn shit?
O.B.: Willard's wife.
Willard: Well, make your own goddamn masks!
Spencer 'Big Daddy' Bennett: Look, nobody's sayin' they don't appreciate what Jenny did!
Tennessee Redfish: Well, if all I had to do was cut a hole in a bag, I coulda cut it better than this!
O.B.: What about you, Robert? Can you see?
Robert: Not too good. I mean, if I don't move my head I can see you pretty good, more or less. But when I start ridin', the bag's movin' all over, and I'm ridin' blind.
[one of the men takes off his mask and tries to rip a larger eye hole]
Bag Head #2: Shit. I just made mine worse. Anybody bring any extra bags?
Bag Head #3: No! Nobody brought an extra bag!
Bag Head #2: I'm just askin'!
O.B.: Do we have to wear 'em when we ride?
Spencer 'Big Daddy' Bennett: Oh, well, shitfire! If you don't wear 'em as you ride up, that just defeats the purpose!
Tennessee Redfish: Well, I can't see in this fuckin' thing! I can't breathe in this fuckin' thing, and I can't ride in this fuckin' thing! [he takes the mask off]
Spencer 'Big Daddy' Bennett: Now, look, let's not forget why we're here. We got a killer nigger over that hill there! And we gotta make a lesson out of him.
Bag Head #2: Okay, I'm confused. Are the bags on or off?
Robert: I think we all think the bag was a nice idea. But, not pointin' any fingers, they coulda been done better. So how about no bags this time, but next time we do the bags right and then we go full regalia.
Tennessee Redfish: You get my vote, Robert. [everyone takes off their masks]
Spencer 'Big Daddy' Bennett: Wait a minute! I didn't say "no bags"!
Bag Head #2: But nobody can see.
Spencer 'Big Daddy' Bennett: So?
Bag Head #2: So it'd be nice to see.
Spencer 'Big Daddy' Bennett: Goddamn it, this is a raid! I can't see, you can't see — so what?! All that matters is can the fuckin'horse see! That's a raid!
When they are riding dramatically over the hill, if you watch and listen closely, you'll notice that one of them actually falls off his horse as they're galloping down the hill.
Schultz's reaction when he discovers Django's wife has a German name.
Django's first meeting with Broomhilda in Candie's place.
Django: Hey there, little troublemaker.
(Hildy stands in stunned silence, then drops her glass of water, and finally faints)
Schultz: You silver-tongued devil, you.
Stephen's expression when Lara says she doesn't want Hildie's whipping scars at the dinner table; he is utterly indignant and almost shocked that she doesn't want to see it.
The first fight in Candieland. Schultz just died, the Dragon's been offed, Django is mowing down plantation workers...and there's one guy who bursts through the doorway, gets shot in the leg, and proceeds to get shot again and again without dying. Even funnier was the lawyer screaming for help about them being under attack prior to being shot in the back by Django.
Also crosses the line twice was a point where Django guns down some Mooks - and one of them isn't instantly killed, and still keeps screaming throughout the fight. Even after he gets both hiskneecaps shot off, has a fat Mook fall on top of him and is still alive by the time Django is forced to surrender! This means he's either the luckiest or UN-luckiest of the Mooks in that shootout!.
There is also a bit of fridge brilliance in it. Cora most likely has flat shoes as house worker, while Sheba as mistress has heeled shoes. Likewise Cora has to do work in the house so she should be much fitter than Sheba whose job is to look pretty.
Stephen trying to intimidate Django by saying that he counted six shots, meaning Django used up all his bullets. Django then pulls out a second gun.
Stephen: I count six shots, nigga.
Django:(pulls out second gun) I count two guns, nigga.
The revelation that Stephen can walk and talk just fine and that how he presented himself previously was all an act. It leads the view to expect that one big last brawl is coming between him and Django. Nope.
Pretty much the entire last couple minutes of the film are a strange mix of funny and awesome, especially when Django calmly walks out of the mansion, puts on his sunglasses, and watches the whole damn thing go up in flames. Capped off by the adorable Broomhilda covering her ears and watching her husband with pride. Django even makes the horse do a "refined" walk while riding it, for both fun and to further piss over the people he just killed.
Django's truly epic trollface◊ at the end of the film after he blows up the Candyland plantation building also qualifies.
