I'm playing the SCAP since late 2006, and we just got past midpoint (my players are reaaaaaally slow...). We had a lot of glorious moments in those three years, though. Here's some.
[WARNING - some various spoilers ahead]

The final battle in the Malachite Fortress is proving too tough for the party. His high AC, regeneration and ugrosh make Kazmojen nearly unstoppable, and five out of six PCs are on the ground, dead, dying or otherwise incapacitated.
Only Eyleen, the elven sorceress, stands his ground in single-digit HPs [ie completely unharmed, being a second-level sorceress ;)], while the slaver is about half-sane and approaching her with a killer grin on his face, his ugrosh dripping her camerades' blood.
She has this newly found wand, whose flame marks all over its lenght suggest some kind of Fire power. No command word, though. But, wait! A closer examination of the flame marks [and the wise expenditure of a Hero Point] shows the marks are made with tiny letters forming a word repeated again and again! Maybe...
"DIEYOUBASTARD!!", yells Eyleen, pointing the wand against the half-troll. A jet of bright red flames spouts from the raised wand, striking Kazmojen in the middle of chest, this unexpected resistance scorching as much as astounding him, his ugrosh falling on the ground.
"DIEYOUBASTARD!!", yells Eyleen again, promply seizing his enemy faltering. The flames engulf Kazmojen again, his blistering wounds unable to close. Enraged, Kazmojen throws an axe, opening a large slash on Eyleen flank, which leaves her with 3hp.
"Die...You...Bastard!!", pants Eyleen, desperately clutching the wand. And once again, the wand reacts, the fire ignites, the troll screams... this time, falling on the ground, motionless!
[Eyleen then leaved the Fortess, rushed to the St. Cuthbert church and got healed, then led Alek Tercival and a couple of Cuthbertians to recover his fellows and the kidnapped kids. Days later, the party was celebrated in a public ceremony by the Lord Major, which christened them officially as "The Eyleen Band", and granted them a tax-free residence on Ash Avenue. It's worth mentioning that the girl playing Eyleen the Sorceress was at her first D&D experience ever.]

When a couple of porters delivers a big, rich chest to their new home, saying the Lord Major wants to add a personal rewards for their services to the said new home they received on the City behalf, the PCs are flattered and just a little suspicious, but put it nevertheless in their living room.
Their suspicion level raises dramatically next morning, when they wake up to discover the chest has disappeared overnight, with no signs of burglary. Then, they find a new four-poster bed in a unused room.
Prodding the bed with a spear, they discover that it was actually the mimic they bargained with to free Ghelve's familiar in Jzadirune. Since then, they have that mimic as a guard "dog", and actually hired an old croonie to prepare him some food (it's especially fond of turkeys) while they're away.
[In the time, the mimic posed as a table, armchair, doorframe, piano, lacunar ceiling, harp, to the delight of the old croonie... :)]

"Ehi, wait, the sign on that door reads 'No fire beyond this point', maybe we shouldn't throw fire here..."
"Don't worry, I'm staying clear from that door... it's THIS moldy door here we need to break down!"
[Brown mold nearly reached the Lucky Monkey's kitchen -- five PCs succumbed to the subdual damage, the sixth managed to get them out of the cellar somehow]

The noise of battle draws Triel Eldurast out of her room, to join his thugs in the fray against the PCs, which however fare very well and quickly drops a handful of Alleybasher, forcing Triel to retreat back in his room, closing [but not locking!] the door behind.
Eager to press their enemy, the Rogue sprints to the door and pushes it. The trap sprungs, slashing the Rogue and pinning him in the doorframe, where he can't help but watch Triel fully healing herself in a couple of rounds.
Enters the party Barbarian!, who just dropped the last thug and jostles vigorously the door. The door opens just enough to unpin the Rogue, which deems wiser not to risk being trapped alone in the room with Triel, and hence steps back in the corridor. The door closes again.
The Barbarian jostles harder, opens the door, steps forward, get pinned himself and suffers two square hits from Triel's flail, dropping to 0hps. The other PCs rush to the door and try to open it but fail.
The Barbarian decides to push and manage to open the door before falling to the ground unconscious, his body preventing the door to close once again. Finally able to enter the room, the party drops Triel in just two rounds.
[My players barely remember Triel today, but everybody recall vividly "That damned door!"]

Still in the Kopru ruins, the party is already weared after the battles against the T-rex skeleton and the large spider zombies, but they simply CAN'T ignore that last cave with the big stone slab that could be hiding "the treasure".
So they enter the cave, turn undeads exhausted, and what could have been a thrilling (for the Kyuss Spawns worms menace) but manageable encounter turn out a near TPK.
The Monk succumbs to the fear aura and runs away, heading squarely to the nearest Glyph of Warding, which goes boom! and put him in negatives. The Cleric goes down and is worm infected, the party rogue is down, everybody but the Barbarian in single digits. "Flee!" yells the Sorceress, heading for the exit.
The Druid grabs the Rogue, while the Barbarian fends off one Spawn before retreating, glimpsing the other spawn drawing the Cleric in a niche at the far end of the cave...
They spend some days recovering, healing two of them from the Kyuss's Gift, and equipping themselves at Skie's. Upon hearing their tale, Skie asks them to get her an alive worm to study, for 1.000GPs.
Returning to the cave after recovery (which included healing two of them from the Kyuss's Gift), the party is obviously greeted by TWO Spawns, one of them being the unfortunate Cleric. This time, being well prepared and at full strength, they manage to kill the Spawns quite easily.
They manage to get the worm for Skye, and are about to leave, when the Sorceress says "We've already failed Fairax [the Cleric] once, we cannot leave him here again...". The party looks dismayed at the two puddles of green goo that the Spawns had dissolved to, then the Druid fetches two small bottles from his knapsack, labels them "A" and "B" and fills up each from a different puddle.
They then head to the Kord church and deliver there the bottles, saying they're truly sorry but they "can't tell which one is the Goo formerly known as Fairax, albeit one of those surely is", then leave.

The party fells for the Kuo-Toa ferry-keeper trick, gets dumped in the water and attacked. Being totally unprepared to battle in the water, they have to retreat hastily and somehow manage to. So obviously they recover and plan for vengeance, cheering the moment they will encounter that "froggy bastard" again.
Well, despite all their planning, they underestimate by far the "froggy bastard"in HIS natural environment [not mentioning him being a 5th level monk, anyway], so the ferry-keeper manages to kick the hell out of them once more, single-handedly!
[In their third attempt, they managed to evade the ferry-keeper and finally entered Bhal-Hamatugn, where they were repeatedly beaten, incarcerated and variously humiliated by the other Kuo-Toa. The Kuo-Toas, especially the ferry-keeper Kuo-Toas, are now the archetipal invincible bad guy of our campaign]

When Kristof the Pelorite went mad at the new Wee Jas spire shadowing his shrine, obviously the party felt compassionate with him and really wanted to do something for him.
As the events leading them to Karran-Kurral unfold [in an expanded way, see here], they deactivate an artifact in Liduton, causing a side-effect cave-in just under the Wee Jas cathedral in Cauldron. While the cathedral doesn't collapse, it tilts a little to one side, just enough to cast its spire shadow away from the Pelor shrine.
