Nothing to put here, Just curious.

Long ago in an AD&D game, I was running Against the Cult of the Reptile God. The party located a secret door that led them directly to the chamber with the naga. A TPK resulted with many lolz after I explained exactly what they had done and to this day any shortcut leading to tremendous difficulty is referred to as "straight to the naga".

I have more than I can count. Two recent ones came from Call of Cthulhu, thanks to a new player who hadn't still grasped the concept of "no phones".

Average scene in CoC. The player playing the sheriff was speaking when he stopped all of sudden and addressed this new player.

"Frank?" (not the real name)

"Yes?"

"I have laid out our plan. Did you understood it? Can you repeat what our plan is?"

"Er... No."

"Because I still have to lay out our plan!! PAY ATTENTION! PAY ATTENTION!!"

* * *

Same player. He ended up being chased by the Dead Light (a light that devours you, don't ask) along a road at night.

The rest of the party was on a car, managed to get ahead of the Dead Light and, even if it wasn't Pulp Cthulhu, they managed to open a door (it was a big car for operations in the field), grab the character, pull him inside and speed away - all of this without stopping. This of course involved  a lot of die rolls but made for a memorable scene.

"OK Frank", I say, "Now you are inside the car."

"I wasn't already inside the car? Why only now?"

Total silence.

"No," I said, in my most vanilla tone. "My mistake. You were inside the car. You have been chased by the Dead Light INSIDE the car for ten minutes, and luckily you managed to avoid it by jumping from seat to seat."

"But... I don't remember doing this..."

The Sheriff "BECAUSE. YOU. WERE. RUNNING. ON. THE. ROAD. PAY ATTENTION!! PAY ATTENTION!!"

Frank still fiddles with his phone but he is the youngest of the group, so I guess that it is the curse of his generation. Pity, because he is an excellent role-player (which is why he is still with us).

I don't know if it's an in-joke so much but...
Early 80s during the satanic panic my group is playing. My mother comes up with a newspaper:

Mom: Some kids were playing D&D and one shot the other. The one that was shot tried to use a shield spell to protect himself, is that what happens in this game...
Friend: What an idiot, should have used protection from normal missiles spell.

My mom was aghast until we all started laughing then she left a bit embarrassed.

My GM has the worst rolls ever, so he rolled a Hydra to throw at us, from the description it looked likean undead Hydra, we we're still low level (3rd level IIRC) I cast summon monster 1 and get giant leeches 3 I think, so send them against the monster and they manage to kill it with their fist blood drain attack. Still funny to ask if the monster is a Hydra to this day.

Different session, I start drinking earlier and keep on drinking, so we find some Stone Giants and stupid/drunkish me forgets they have magic immunity so I throw magic missile at them, we lost our followers squashed under a boulder, still get ribbed about not drinking BEFORE the game starts.

Plenty more just from our current 2+ years AD&D2e campaign.

Way back when, playing WEG SW, someone used the Force to push insted of pulling and killed the diplomat we were trying to rescue, he couldn't get us to stop ribbing him about it.

I throw slimes, jellies, and puddings at the party so often that when the magic-user in the group starts to collect ... ichor...for the alchemist they have on hire in town to use in admixtures, someone usually quips "Great. Someone sneezes and you wanna keep it."

This happened to me twice. Once in GURPS Space (a cross-over between Star Wars and Battlestar Galactica, with strong manga vibes). The second time in Star Wars D6. Both players were female.

GURPS: "I want to play a young with mysterious psychic powers. Long, flowing hair, flowing robes... and she plays a laser harp, whose music can affect minds!" (OK, cool!)

Star Wars: "I want to be the diplomat, capable of defusing situations, creating alliances... moving a bit in the shadows." (Cool! A finally a bit unusual character!)

BOTH GIRLS, DESPERATE, AT THE VERY FIRST FIGHT: "Where is my BIG BLASTEEEEEEER??" (they both got one and used only it for the rest of the campaign - even if their characters' skill was nil.)

This happened five years apart. Yet, same start, same ending. Sometimes I wonder how people think.
