Durarara!!: Shinra, after Izaya trolls him by handing his cellphone number to the police.
Izaya: How was it? Gave you quite the adrenaline shot, didn't it? Did you and Celty just grow to love each other even more due to the misattribution of arousal? Shinra: Ah hah hah. Go die chest-first in a clay ice shaver, Izaya.
In the anime adaptation of Fairy Tail, Happy and Lucky break out into laughter while chopping firewood. Then Lucky screams at Happy to stop laughing.
In The Sandman there's a scene where Lucifer is asked if he would ever return to Hell. He stares for a moment and then says exactly this.
There's a very sinister example in The Lives of Others, which is set in communist East Germany. A young Stasi agent in training is telling a (quite funny) joke to some of his friends that could be interpreted as being anti-government. A Stasi captain overhears it, and when the joke is finished, he laughs heartily... and then asks for the joke teller's name and rank, presumably so that he can be fired or imprisoned. And then he says he was just kidding, tells an even more anti-government joke, and leaves the stunned jokester be.
In The Clones of Bruce Lee (which is about, you guessed it, Bruce Lee clones), the villain Dr. Ni gives a hearty laugh, then immediately yells "Silence!" at all his henchmen laughing with him.

In the Spider-Man Trilogy, there's also a scene that has been used by many to emphasis this trope, with J. Jonah Jameson laughing at Peter Parker's claim before asking, "You serious?". Seen here
Billy Madison. The title character delivers a pretty great variation:
Carl: ...I see you got a little sun today. Billy: Oh you think so? I fell asleep by the pool for a few hours. Eric Gordon: Did you fall asleep or did you pass out? Billy: Hahahahaha SHUT UP!
In Wayne's World, this is Wayne's reaction when Garth asks "did you ever find Bugs Bunny attractive when he dressed as a girl bunny?"

Live Action TV
In "Last Laugh," a M*A*S*H episode, Hawkeye and BJ arrive (drunk) at the Swamp from a court martial caused by a practical joke. As the "friend" who played the trick is leaving in a jeep they loaned him, they get a bill for his antics for $580. They both laugh for a few seconds before Hawkeye abruptly stops and gets mad. However, it's a subversion, as BJ cheerfully explains that the joker will have to walk back to camp in 30 minutes because "the only thing gassed up in that jeep was us!"
Another episode has Col. Potter trying to bring a meeting to order when Hawkeye makes a lame joke. Potter, laughing, says "Pierce, sometimes you can be very amusing," and then abruptly stops and says "And then there's now."
Used many, many times by Uncle Phil in The Fresh Prince of Bel-Air. The laugh rises up into a high pitched, somewhat creepy register, but he loses the exclamation on "No", and goes straight into thunderous shouting. For example, in one episode Will and Carlton lose Vivian's bracelet which they pawned for a stock investment that quickly tanked. Phil finds out about this and starts laughing which the boys join in. When asked by Phil what he should do, Will jokingly replies he should "reward them for their honesty... it worked for The Beav" causing Phil to laugh louder.
He makes a suggestive comment about Zoe, who laughs and replies cheerfully "I can hurt you."
He does the same thing regarding Inara, who has a similar response.
Mad Men has a hilariously cryptic example when Bert Cooper asks Duck Phillips, who's up for a job with the company, whom he's voting for. Duck good-naturedly answers that if he says Nixon, Cooper will think he's sucking up, and if he says Kennedy, he'll want to reform him, so he'll say... Nixon. "That's nice to say," Cooper responds with a smile — which abruptly disappears... and then abruptly reappears — and then abruptly disappears again. Duck just stands there looking bewildered until he's led away.
Buffy the Vampire Slayer. Giles is none too pleased to learn that Angel, nearly tortured him to death the last time they met (after murdering his girlfriend a few months earlier), is still alive. He's even less pleased when Angel shows up at his doorstep.
Angel: I'm sorry to bother you.
Giles: (Stares, then bursts out laughing). Sorry. That's just rather funny, coming from you. (Chuckles) "Sorry to bother me."
Angel: I need your help.
Giles: And the funny keeps on coming.

Get Fuzzy. In the strip for 9-27-13, Bucky has been trying to become a superhero by attaching bat wings (from a real bat) to his back and donning a bizarre costume. He asks Satchel his opinion as to his success.

Satchel:: Short answer?
Bucky: Long answer?
Satchel:: Ha Ha Ha Ha Ha Ha Ha Ha Ha Ha Ha Ha Ha...No.
Cyrano invokes this trope at Act I Scene V when he considers the possibility that an ugly man could love.
Le Bret(stupefied): How now? What? Can it be...?
Cyrano(laughing bitterly): That I should love?...
(Changing his tone, gravely): I love.
De Guiche plays it straight at Act II Scene VII when he reveals to the multitude that celebrates Cyrano combat against a one hundred men that he was the man who hired them against a poet for a satiric poem:
Red vs. Blue: Washington delivers the Trope title (in full snarking mode) when Doc suggests the Reds are behind a well thought through trap. Made quite creepy by the fact that Washington never laughs otherwise. Its probably for the best.
There's also a very early example with Caboose, of all people.
Tucker: I'm sorry, what? It's kind of hard to hear you over the sound of your constant team-killing. Caboose: Ah ha ha ha ha ah ha yeah ah hah—Don't make me mad.
Counselor: Ain't no such thing as too young! You're just too old!
Black chef: (boisterous laugh)

Phelous once did a unique variation on this, when reviewing the "funny" version of House of the Dead. There was a scene where it suddenly started playing in reverse for no reason. Phelous laughed out loud, heartily; then the video reversed to before he started laughing and he said "Actually that's not very funny at all."
Linkara did this in his reviews of "Doom's IV #2" and "NBComics #1", laughing in response to the sexist jokes in both comics before yelling "This comic sucks!"

The episode "The Bart Wants What it Wants" has this:
Ranier: Bart, your little tie makes me smile. Bart: Excuse me, but you don't sound as tough as you do in the movies.

Episode "Lisa on Ice":
Homer: OK son, just remember to have fun out there today. And if you lose, I'll kill you! [everyone laughs] Bart: [good-humored] Oh, Dad. Homer: [looks menacingly at Bart] Bart: [cringes]
Also from the episode where Homer becomes trash commissioner, and has to deal with (actually, ignore) the garbage crisis: Homer is about to leave Moe's. When Moe asks him to pay for his drinks, Homer says his campaign catchphrase: "Let someone else do it." Moe laughs, amused. Homer starts to walk out. Moe cocks his shotgun: "Seriously, give me the money."

This happened behind the scenes on MythBusters. They were testing whether certain sugary breakfast cereals are in fact less nutritious than the box they come in. The test involved three groups of mice: a control group (A) being fed standard mouse food, a group (B) being fed sugary cereal, and a group being fed cardboard processed into mouse-food-like pellets (group C). All three groups of mice did fine all week. Then everyone left for the weekend. When they returned on Monday, there were no longer three mice in group C. Instead, there was one very fat mouse and two mouse skeletons. When the team showed the footage to Discovery Channel executive types, this was their reaction in a nutshell.
