Dumbledore: You may have noticed a few changes around school? Harry: A FEW! WHAT THE BLOODY HELL HAPPENED WHILE I WAS AWAY? WHERE'S EVERYONE'S BLOODY CLOTHING? ARE YOU ALL MAD!? Ron: 'arry, that's just not polite.
You're giving me a time machine to treat my sleep disorder.
You're giving me a TIME MACHINE to treat my SLEEP DISORDER.
YOU'RE GIVING ME A TIME MACHINE IN ORDER TO TREAT MY SLEEP DISORDER.
"Ehehehehhheheh..." Harry's mouth said. He was now holding the necklace away from him as though it were a live bomb. Well, no, not as if it were a live bomb, that didn't begin to describe the severity of the situation. Harry held the necklace away from him as though it were a time machine.
In the Disgaea fanfic Disgaea Jewel of the gods Adell is this, due to Laharl and Mao often arguing all the time, or being crazy.
Mao is this when Laharl and Adell are being too Hot Blooded.
For what seemed like the millionth time, Stan was forced to act as peacemaker. "Cartman, shut up. Kyle, calm down. Kenny, this isn't funny." He pinched the bridge of his nose.
Subverted in Shinji and Warhammer 40K, where Ritsuko's attempts to make sense of the increasingly physics-breaking powers Shinji develops from the AT-field and the other incredibly odd events happening around her.....end up driving her insane.
Played straight in Bagenders with Legolas (and possibly Sam), Aragorn being somewhat neurotic, Frodo being insane, Gandalf being a Dirty Old Man, as are Merry and Pippin, Gimli is rarely seen, but has installed anti hobbit defence mechanisms in his room.
Zuko in the Avatar: The Last Airbender fanfic The Boiling Rock definitely fits it. If he's not breaking the Fourth Wall, he's mentioning how the story is nothing but a world of madness that he is trapped in.
SORA: AM I THE ONLY ONE WHO SEES THE MASSIVE ORB OF PURE EVIL ABOVE US RIGHT NOW? AND HOW THE HELL DO YOU HAVE AN ANY IDEA WHAT THE FUCK IS GOING ON? I'M THE ONE WHOSE BEEN HAVING PROPHETIC, MATRIX-LIKE DREAMS!

In almost any Sonic the Hedgehog fanfic, that stars Team Chaotix, Espio will be this.
Hitsugaya in Uninvited Guests is the only one who doesn't operate under Insane Troll Logic or alcoholic madness. Well, before he snapped that is.
In the Mass Effect fanfic Inglorious Bosh'tets, Tali'Zorah has the unenviable task of trying to manage a crew of idiotic and insane Quarians, all of whom blame her for pretty much everything.
Shinji Ikari in Nobody Dies, who is basically a well-adjusted and sane version of his canon self. Everyone else is totally weird.
Even though Kyon and Chisame have had their backstories revised when they're brought into The Emiya Clan, they retain their personalities perfectly. Everyone else in the Clan is insane, weird, perverted, or otherwise, while these two struggle but usually succeed to keep their sanity amidst a household where random explosions, Eldritch Abominations, and harem antics are considered normal.
Going by Nasuverse stats, Kyon has EX rated Common Sense. Chisame has A+.
Andy from Calvin & Hobbes: The Series eventually became this after initially being The Generic Guy. He's usually the only one who can keep everyone in the group from arguing.
